Here's a more useful example, just in case I seem too sarcastic :-)

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextArea;
import javax.swing.SwingUtilities;

public class ABigTextAreaAndSomeButtons implements ActionListener {

     private static final String THIS="This", THAT="That", OTHER="Other";

     private JTextArea area = new JTextArea(40,80);

     public static void main(String[] args) {
         SwingUtilities.invokeLater(new Runnable() {
             public void run() {
                 new ABigTextAreaAndSomeButtons();
             }
         });
     }

     ABigTextAreaAndSomeButtons() {
         JPanel p = new JPanel();
         p.setLayout(new BorderLayout());
         p.add(area, BorderLayout.CENTER);
         JPanel bp = new JPanel();
         bp.add(makeJButton(THIS));
         bp.add(makeJButton(THAT));
         bp.add(makeJButton(OTHER));
         p.add(bp, BorderLayout.SOUTH);

         JFrame f = new JFrame("A big text area with some buttons");
         f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         f.add(p);
         f.pack();
         f.setVisible(true);
     }

     private JButton makeJButton(String label) {
         JButton b = new JButton(label);
         b.addActionListener(this);
         return b;
     }

     public void actionPerformed(ActionEvent e) {
         String command = e.getActionCommand();
         area.append("\n" + command);
         if (OTHER.equals(command))
             area.append(" **bonus** ");
     }

}
