Im trying to make a hangman game in java using JPanels and labels, but I am struggling to get all of my panels showing up. I have to make a drawing of the hangman in a panel below the text field, but when I run my code the text field takes up the entire GUI and doesn't show my drawing at all. If anyone can help that would be great. Heres my code.

A JPanel is opaque by default so you see a grey background.
You need to use:
panel.setOpaque( false );
if you add a panel to your component containing the background image.
By the way you should NOT be using static variables. Look at the examples from the Swing tutorial for a better way to create your frames. That is create a class to represent your game. This would be a JPanel. Then you define all the variables you need for you game in this class. Then you simple add the panel to the frame. You should NOT be createing components in the main() method.
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.

As PeterMmm stated arrayLists should be able to solve your predicament. ArrayLists allow you to make an array of any type very easily and has a very nice interface such as
mylist.add(element)
Maroun Maroun also made a valid point that you can approach this much more nicely using a loop so that you can avoid the large amount of repitition in your code, but its not necessary to do so if you are happy with it.
Hopefully the following sample of using ArrayList can help you:
http://javarevisited.blogspot.de/2011/05/example-of-arraylist-in-java-tutorial.html
And if you want more information about arraylist here is the docs:
http://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html
My last tip, while looking at your code is to add an actionListener to your button, as currently it does nothing ;)
ent.addActionListener(new ActionListener()
{
#Override
public void actionPerformed( ActionEvent e )
{
//..do stuff here or call a function to do stuff :)
}
});
You might want to check out putting this into a bigger loop. You could set up a loop and then use generic statements to add Labels and size them instead of adding a different Label object for each one. It would cut about 20 lines of code.
EDIT: By loops I was talking about how to deal with setting bounds and adding to the panel. An example would be something like
while(condition)
{
panel.add(new JLabel(information).setBounds(bounds));
}
This gets rid of the repetition of having code like:
JLabel p1 = new JLabel(info);
JLabel p2 = new JLabel(info2);
...
panel1.add(p1);
panel1.add(p2);
...
p1.setBounds(bounds1);
p2.setBounds(bounds2);
...

I ran your program in Eclipse and it seems to run fine....no errors ! Download IDE such as eclipse or anything that you like and try to run the program from there.
