Hi,
extends JFrame is application.
If applet extends JApplet.
Here is an example of the application.
Please run this way java Kbc test.jpg
test.jpg is the background image. Please change file name.
public class Kbc extends JPanel implements ActionListener {
private JButton b1, b2 , b3 ;
private JLabel l ;
static private String filename ;
private Image image ;
private JLayeredPane layeredPane ;
public Kbc() {
     layeredPane = new JLayeredPane() ;
     layeredPane.setPreferredSize( new Dimension(1100,700) ) ;
l=new JLabel(":Wellcome :");
Font f = new Font("Dialog", Font.PLAIN, 24);
l.setFont(f);
l.setBounds(300,30,1100,20);
layeredPane.add(l, new Integer( 3 ) );
b1=new JButton("START");
b1.setFont(f);
b1.setPreferredSize( new Dimension(200,100) ) ;
b1.setSize( b1.getPreferredSize() ) ;
b1.setLocation(350,100) ;
b1.addActionListener(this) ;
layeredPane.add(b1,new Integer( 1 ) ) ;
b2=new JButton("QUIT");
b2.setFont(f);
b2.setPreferredSize( new Dimension(200,100) ) ;
b2.setSize( b2.getPreferredSize() ) ;
b2.setLocation(350,210) ;
b2.addActionListener(this) ;
layeredPane.add(b2, new Integer( 2 ) ) ;
b3=new JButton("HELP");
b3.setFont(f);
b3.setPreferredSize( new Dimension(200,100) ) ;
b3.setSize( b3.getPreferredSize() ) ;
b3.setLocation(350,320) ;
b3.addActionListener(this) ;
layeredPane.add(b3, new Integer( 5 )) ;
add( layeredPane);
public void paintComponent (Graphics g) {
          super.paintComponent(g);
try {
File f = new File(filename);
BufferedImage image = ImageIO.read(f);
g.drawImage(image, 0, 0, this);
} catch (Exception ex) {
ex.printStackTrace();
public void actionPerformed(ActionEvent e) {
if (e.getSource()==b1)
// new Start1();
this.setVisible(false) ;
else if (e.getSource()==b2) {
System.exit(0);
} else if (e.getSource()==b3) {
JOptionPane.showMessageDialog(this,"RuLes");
public static void main(String args[]) {
filename = args[0] ;
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
private static void createAndShowGUI() {
System.out.println("Created GUI on EDT? "+
SwingUtilities.isEventDispatchThread());
     Kbc k=new Kbc();
JFrame frame = new JFrame("Kbc");
     frame.add(k);
frame.pack();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setPreferredSize(new Dimension(1100, 700 ) );
frame.setVisible(true);
}
