Image and JButton don't come out at the same time

It hasn't been long since I started developing Java.
This code was run by Eclipse. When I run this code javaSE-1.8, only mimage appears, and when I remove and run 'paintComponenets(g);',quit button and start button appear, and mimage disappears. I think 'paintComponents' is the problem. How do I solve this problem
public class Mainscreen extends JFrame {
private Image screenImage;
private Graphics screenGraphics;
private Image mImage = new
ImageIcon(Main.class.getResource("../img/unnamed.jpg")).getImage();
private ImageIcon quitEnter = new
ImageIcon(Main.class.getResource("../img/startButtonBasic1.jpg"));
private ImageIcon quitBasic = new
ImageIcon(Main.class.getResource("../img/startButtonEntered1.jpg"));
private ImageIcon startEnter = new
ImageIcon(Main.class.getResource("../img/startButtonBasic.jpg"));
private ImageIcon startBasic = new
ImageIcon(Main.class.getResource("../img/startButtonEntered.jpg"));
private JButton quitButton = new JButton(quitBasic);
private JButton startButton = new JButton(startBasic);

When I press some button all JFrame changes except the cells of JTable, containing my custom JPanel.
I tried forcing only the first cell...
changeLAF((JPanel)table.getModel().getValueAt(0, 0), "javax.swing.plaf.metal.MetalLookAndFeel");
But I got Exception:
Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: PanelSpinnerRadioButtonData cannot be cast to javax.swing.JPanel

The limitation of the SwingUtilities#updateComponentTreeUI(...) method is that the cell renderer LookAndFeel can not change
Since PSRBTableCellRenderer does not extends JComponent, it is not subject to LookAndFeel update in the SwingUtilities # updateComponentTreeUI (...) method
// #see javax/swing/SwingUtilities.java
public static void updateComponentTreeUI(Component c) {
updateComponentTreeUI0(c);
c.invalidate();
c.validate();
c.repaint();
}
private static void updateComponentTreeUI0(Component c) {
if (c instanceof JComponent) {
JComponent jc = (JComponent) c;
jc.updateUI();
JPopupMenu jpm =jc.getComponentPopupMenu();
if(jpm != null) {
updateComponentTreeUI(jpm);
}
}
Component[] children = null;
if (c instanceof JMenu) {

children = ((Container)c).getComponents();
}
if (children != null) {

You can avoid this by overriding the JTable#updateUI() method and recreating the cell renderer and editor.

frame.add(MainPage());
This line builds a brand new "main page" JPanel, and adds it the the JFrame.
frame.remove(MainPage());
This line of code creates a brand new "main page" JPanel, which has never been added to the JFrame, and attempts to remove it.
This new panel can't be removed, because it was never added. You need to retain a reference to the original panel, and remove that.
JPanel main_page = MainPage();
frame.add(main_page);
//...
frame.remove(main_page);
Note: This main_page could be re-added at a future time without needing to recreate it. Just call frame.add(main_page); again. But really, you want to use the card layout manager.

How to randomly assign words in a Hangman game in JFrame?

So I am doing a Hang man game in Java for my Final Project in my Computer Science class. I have done the template for the Hang man (i.e. buttons and added the words needed). But I don't know how to draw the Hangman itself and how to randomly add the words (meaning so they will start guessing the words) to the program. What I am asking is how do I draw the Hangman if a letter was guessed wrong(or right, to write in the textfield). For the letters I have done JButtons because I think it would be easier, and added action listeners. I know the code is very long, but don't pay attention to the template, method Start is where I have my words and hints. Thank you in advance. Don't mind that I do not have a main method, I have a driver class that extends this class. (It was one of the requirements)
Solved!

To draw the lines you could use drawline in the Graphics class.
g.drawLine(int x1, int y1, int x2, int y2);
Docs:
Draws a line, using the current color, between the points (x1, y1) and (x2, y2).
Write down the coordinates to a int array and loop thought that array for all cords.
int[] line1 = new int[]{x1,y1,x2,y2};
int[] line2 = new int[]{x3,y3,x4,y4};
If you wonder how to draw the head you can use drawPolygon
int[] head = new int[]{x,y};
final int headSize = 50; //width and height in px
g.drawPolygon(head[0], head[1], headSize, headSize);
Hope it helped.

I want to add, move and set properties (font and rotation) of components at runtime.
In other words, I need to add a button, a label, drag them using mouse and set a component's properties at runtime. Is there any example Java swing for or similar to this?
This is my code :

Years ago I wrote a framework for this. Maybe it can serve you as a start (the library is Open Source):
Tutorial: http://softsmithy.sourceforge.net/lib/current/docs/tutorial/swing/customizer/index.html
Javadoc: http://softsmithy.sourceforge.net/lib/current/docs/api/softsmithy-lib-core/index.html
Homepage: http://softsmithy.sourceforge.net/
Maven:
<dependency>
<groupId>org.softsmithy.lib</groupId>
<artifactId>softsmithy-lib-core</artifactId>
<version>0.2</version>
</dependency>
More info: http://puces-blog.blogspot.ch/2012/07/news-from-software-smithy-version-02.html
Other solutions:
You could consider the NetBeans Platform and try to reuse either its Matisse component or the Visual Graph library.
