Radio Button does not appear in JFrame

My JRadioButton does not appear in the JFrame.
It should appear below the Method of payment. If the user picks the creditRadioButton, the creditCardLabel and the creditTextField appears.
Code:

}
public static void main(String args[]){
fin.setVisible(true);
fin.setResizable(false);
fin.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
fin.setSize(500,400);
}
}
The output:

You did not add buttons[0] and buttons[1] to the panel. Try to add them after this line add(methodLabel); and check the result.
add(buttons[0]);
add(buttons[1]);

Swing program exits immediately after starting

The program will launch but then immediately quit. Also, I'm not quite sure if adding multiple panels to a class that extends JFrame is allowed.

Your program throw multiple NullPointerExceptions. You declare many objects as class fields and then never initialize them. You need to add at least:
inputPanel = new JPanel(); in constructor,
panel = new JPanel(); in buildPanel();
and in case of all yours JTextFields, change from:
JTextField field = new JTextField();
to:
field = new JTextField();
But it is only beginning because you GUI doesn't display most of components. You need to choose LayoutManager, and work with it. You add all your panels to center of your frames BorderLayout and I think they overlap . So for example, to see your JTextFields, JLabel and JButton, you can change add(component); in constructor for:
add(BorderLayout.NORTH, messageBar);
add(BorderLayout.CENTER, inputPanel);
add(BorderLayout.SOUTH,calculateBar);
also add:
panel.setLayout(new BoxLayout(panel,BoxLayout.PAGE_AXIS));
in buildPanel() method, and it will look better.
Whats more, you need to move code for JOptionPane to the end of calcCharges() method, this way it will have access to processed date and it will display proper output. At beginning of a app, it displays only zeros.

Debugging code I have with 2 classes and a JFrame that holds 4 JPanels

I am looking for help to debug this program that I have written there are, no errors but the goal is to create a frame with three panels inside of it each of which has a titled border. I am having difficulty because my prompt requires of me to make 2 constructors and 2 classes so when I call the DailySales class in main I feel it doesn't include the other class.
So basically how can I make the panels show up while still keeping two classes and two constructors and how would I add titled borders to each of the JPanels, sorry but I'm having difficulty with the Oracle tutorial.

JButton exits JPanel

I have multiple cancel, ok, and save buttons. When the user clicks one of these buttons, I need it to exit the JPanel, but not the whole program. I have tried multiple times and everything I do it exits the whole program. My code is below. I know there is a lot of stuff on my code and it can get confusing. Thanks in advance.

I have tried multiple times and everything I do it exits the whole program.
I don't see you code for closing the dialog so I can't guess what you might be doing wrong.
In your ActionListener you would invoke the dispose method on the dialog. The code would be something like:
JButton button = (JButton)event.getSource();
Window dialog = SwingUtilities.windowForComponent( button );
dialog.dispose();
A different approach might be to use a JOptionPane, then you don't need to code your own ActionListeners. You can easily add a panel to an option pane. The code below shows two approaches:
import java.awt.*;
import javax.swing.*;
public class OptionPanePanel
{
private static void createAndShowUI()
{
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo( null );
frame.setVisible( true );
// Build a custom panel
JPanel panel = new JPanel( new GridLayout(2, 2) );
panel.add( new JLabel("First Name") );
JTextField firstName = new JTextField(10);
// firstName.addAncestorListener( new RequestFocusListener(false) );
panel.add( firstName );
panel.add( new JLabel("Last Name") );
JTextField lastName = new JTextField(10);
panel.add( lastName );
int result = JOptionPane.showConfirmDialog(
null, // use your JFrame here
panel,
"Enter Name",
JOptionPane.YES_NO_OPTION,
JOptionPane.PLAIN_MESSAGE);
if(result == JOptionPane.YES_OPTION)
{
System.out.println(firstName.getText() + " : " + lastName.getText());
}
else
{
System.out.println("Canceled");
}
// Let Option Pane build the panel for you
Object[] msg = {"First Name:", firstName, "Last Name:", lastName};
result = JOptionPane.showConfirmDialog(
frame,
msg,
"Enter Name...",
JOptionPane.OK_CANCEL_OPTION,
JOptionPane.PLAIN_MESSAGE);
if (result == JOptionPane.YES_OPTION)
{
System.out.println(firstName.getText() + " : " + lastName.getText());
}
else
{
System.out.println("Canceled");
}
}
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
public void run()
{
createAndShowUI();
}
});
}
}
One problem with this approach is that focus will be on the OK button instead of the text field. To get around this you can use the RequestFocusListener found in Dialog Focus.

Can't figure out how to output result to JLabel instead of System.out.println

I'm stuck again trying to figure out how to out the button clicked to label1.
When I click button01 I get A printed out. I need it to print to the label1 though and say Folder A when A is pressed and B when B is pressed and so on. Any nudge in the right direction?

}

label1.setText("Folder " + e.getActionCommand());

The nudge - and not the full blown answer is this:
Go and read the public API for JLabel
Identify the method that sets the text on JLabel
Instead of checking for an A string value, just set the value of folder to the value of e.getActionCommand().
