lol i think he was talking about formating your messages on the forum.
look at an example that i just created hope it helps. If not then read up on the GUI chapter of your java book.
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JTextField;
import java.awt.BorderLayout;
public class ButtonTest{
    public static void main(String args []){
        JFrame frame = new JFrame();
        JPanel panel = new JPanel();
        final JTextField textA = new JTextField(10);
        final JTextField textB = new JTextField(10);
        JButton button = new JButton("Perform Action");
        class Listener implements ActionListener{
            public void actionPerformed(ActionEvent e){
                if(!textA.getText().equals("") && !textB.getText().equals("")){
                    System.out.println(textA.getText()+" "+textB.getText());
       ActionListener listener = new Listener();
        button.addActionListener(listener);
        panel.add(textA);
        panel.add(textB);
        panel.add(button);
        frame.getContentPane().add(panel,BorderLayout.SOUTH);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.show();
}
