Need a simple GUI

Question

Hi, ive done a java-program that parses and calculates stuff. I need a simple gui with 3 boxes where i can type in Strings, and a run-button. When my program is done, all the gui needs to print "done".
Could someone supply ther code? Have no time to get involved in gui-building :/
tx in advance

tx in advancedepsini, please ignore enc... and the others, they can be a bit cranky at times. I've got a simple program that you may be able to use for your needs:

import java.util.Random;

import javax.swing.border.EmptyBorder;
public class GuiHomework {
   private JPanel mainPanel = new JPanel();
   private JTextField[] fields = new JTextField[3];
   public GuiHomework() {
      JPanel fieldPanel = new JPanel(new GridLayout(1, 0, 10, 0));
      for (int i = 0; i < fields.length; i++) {
         fields[i] = new JTextField(7);
         fieldPanel.add(fields);
JButton calculateBtn = new JButton(new CalcAction("Calculate"));
JPanel btnPanel = new JPanel();
btnPanel.add(calculateBtn);
int eb = 10;
mainPanel.setBorder(new EmptyBorder(eb, eb, eb, eb));
mainPanel.setLayout(new BorderLayout(eb, eb));
mainPanel.add(fieldPanel, BorderLayout.CENTER);
mainPanel.add(btnPanel, BorderLayout.SOUTH);
