Help with making a small game

hello ,
i'm trying to make a small game ,
i never done this before and got mixed up in the menus
i tried to make a background image and it worked
now i'm trying to put a jbutton on the background picture
and it won't show i'm guessing it's not on top
any ideas how to solve it ?

here's what i did to get the background image

Code :

---

 
public class Main extends javax.swing.JFrame {
 
    /**
     * Creates new form Main
     */
    public Main() {
       initComponents();
       jToggleButton1.setVisible(true);
 
       Dimension d= java.awt.Toolkit.getDefaultToolkit().getScreenSize();
       this.setExtendedState(Main.MAXIMIZED_BOTH);
       ImageIcon icon = new ImageIcon("images/c.jpg");
       Image image = icon.getImage();
       image = getScaledImage(image ,d.width ,d.height);
       icon.setImage(image);
       JLabel pic = new JLabel(new ImageIcon(image));      
       this.setContentPane(pic);
       this.pack();
    }

thanks to all helpers !

The posted code does not compile without errors.
Can you make a small simple program that compiles, executes and shows the problem?
