Urgent help on Applet

Hi there.This is my first post here.I need help urgently.
I getting desperate because I got a deadline for a project in 3 weeks time.I'm trying to do a 2 X 2 matrix multiplication applet that simulate systolic architecture.Should be something like the Wallace Tree Simulation. It can be seen here:

I got little knowledge of Java but I have to finish this in 3 weeks time.
Anyone expert in Java that could help me here?
Here it is the code that I did so far:

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.lang.Math;
import java.awt.geom.*;
import javax.swing.border.*;
import javax.swing.event.*;
import java.awt.event.MouseEvent;
import java.net.*;

public class MatrixMultiplication extends Applet{

  Toolkit tk = Toolkit.getDefaultToolkit();
  Dimension d = tk.getScreenSize();
  Button continueButton = new Button("Continue");
  JRadioButton two;
  public int size = 2;
  String name = new String("Matrix Multiplication:  2 x 2");
  Button calculate = new Button("Calculate");
  
  public Button About = new Button("About");
  public Button Help = new Button("Help");

  public void init() {
    this.setBackground(Color.white);
    Panel radioPanel = new Panel();
    radioPanel.setBackground(Color.white);
    radioPanel.setLayout(new GridLayout(9,1));
    two = new JRadioButton("  2 x 2",true);
    two.setBackground(Color.white);
    ButtonGroup radioGroup = new ButtonGroup();
    ButtonGroup radioGroup2 = new ButtonGroup();
    radioGroup.add(two);
    JLabel label = new JLabel("<html>Matrix Multiplication</html>");
    JLabel label2 = new JLabel("<html>Please click continue to simulate</html>");
    radioPanel.add(label);
    radioPanel.add(label2);
    radioPanel.add(two);
    add(radioPanel);
    setLayout(new FlowLayout(FlowLayout.CENTER));
    add(continueButton);
    
    Help.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseClicked(java.awt.event.MouseEvent evt) {
                URL codeBaseURL = getCodeBase();

                try
                {
                    helpURL = new URL( codeBaseURL.toString() + "help.html" );
                    getAppletContext().showDocument( helpURL, "_blank" );

        setLocation( DialogLocation );
    }

    private javax.swing.JScrollPane CentralPane;
    private javax.swing.JEditorPane MainText;
    // End of variables declaration
    
  }
}

I know...the code is a mess...!I can't figure out.
Why doesn't work?
I'm so desperate that I even thought on asking the same thing on experts-exchange but I dunno if they're going to come out with some answer, and I have to pay for it
So any help would be great guys.
Thanks
