I'm going to try GUI programming in Java, but it's going to be messy.

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

public class index extends JFrame{
    private JLabel result;

    ButtonTest() {
        setTitle("Button Test");

        JLabel lab = new JLabel("Click one of the buttons.");
        getContentPane().add(lab, "North");

        result = new JLabel(" ");
        getContentPane().add(result, "South");

        JButton yes = new JButton("Yes");
        getContentPane().add(yes, "West");
        yes.addActionListener(new YesHandler());

        JButton no = new JButton("No");
        getContentPane().add(no, "East");
        no.addActionListener(new NoHandler());;
    }
    class YesHandler implements ActionListener {
        public void actionPerformed(ActionEvent evt) {
            result.setText("you pressed the yes button");
        }
    }
    class NoHandler implements ActionListener {
        public void actionPerformed(ActionEvent evt) {
            result.setText("you pressed the no button");
        }
    }
    public static void main(String [] args) {
        JFrame jf = new ButtonTest();
        jf.setSize(250, 150);
        jf.setVisible(true);
    }
}
