okay..... your main class has to extend JApplet (you can go here to see what you inherit from JApplet class) other than that its MOSTLY the same
EXAMPLE:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class TwoButtons2 extends JApplet {

    //-------------------------------------------
    //
    // init - This method will be called 
    //         to set everything up
    //
    //-------------------------------------------

    public void init() {

	// set up window
        Container window = getContentPane();
	window.setLayout(new FlowLayout(FlowLayout.LEFT));

	// set up red button
	JButton red = new JButton("red");
	red.setBackground(Color.red);
	window.add(red);

	// set up green button
	JButton green = new JButton("green");
	green.setBackground(Color.green);
	window.add(green);

	// set up label
	JLabel which = new JLabel("which one?");
	which.setOpaque(true);
	which.setBackground(Color.white);
	window.add(which);

	// set up listeners
	ButtonListener redLstner =
		new ButtonListener(which, Color.red);
	red.addActionListener(redLstner);
	ButtonListener greenLstner =
		new ButtonListener(which, Color.green);
	green.addActionListener(greenLstner);

	} // end of init method

    } //end of TwoButtons2 class
    
//-------------------------------------------------------------
//
//-------------------------------------------------------------
    
class ButtonListener implements ActionListener {

    // properties
    private JLabel theLabel;
    private Color theColor;
    
    // constructor
    public ButtonListener(JLabel lbl, Color c) {
    
        theLabel = lbl;
        theColor = c;
        } // end of constructor
        
    //-------------------------------------------
    //
    // actionPerformed - called on and sent an 
    //                   ActionEvent and does 'something'
    //                   with it.
    //
    //-------------------------------------------

    public void actionPerformed(ActionEvent event) {

        theLabel.setBackground(theColor);
        } // end of actionPerformed

    } // end of ButtonListener class
