GUI Final Project help

[Unknown]

alright, thanks for answering that, I'll try to split my program up now.

When I tried to separate each part into a different method, it always tells me "invalid method declaration; return type is required". I tried to follow in the same format as my notes and the java sun website. Here's my code so far:

import javax.swing.*;
import javax.swing.border.*;
import javax.swing.BorderFactory;
import java.awt.*;
import java.awt.Color;
import java.awt.event.*;
import java.util.*;
import java.awt.Image;
import javax.swing.ImageIcon;


public class FinalISU implements ActionListener
{
JFrame frame;
JPanel panel;
JLabel title;
JPanel buttonpanel;

public GUI_frame()
{
frame= new JFrame("Cuminating Activity # 2");
frame.setSize(800,350);
frame.setLocation (150,150);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);

panel = new JPanel (new BorderLayout());
}
}

I compared my notes and my source code but I can't seem to find anything wrong.
