Layout Help

Someone help me add a GridBagLayout to my JApplet here is the code i have

Code:

---

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

public class widget  extends JApplet implements ActionListener
{
  JRadioButton optBlue = new JRadioButton("Blue");
  JRadioButton optRed = new JRadioButton("Red");
  JRadioButton optYellow = new JRadioButton("Yellow");
  JLabel lblTitle = new JLabel(" Widgets ");
  JLabel lblWidgetColor = new JLabel(" Widget Color: ");
  JLabel lblQuantity = new JLabel(" Quantity ");
  JLabel lblName = new JLabel(" Name: ");
  JLabel lblAddress = new JLabel(" Address: ");
  JLabel lblCreditCard = new JLabel(" Credit Card: ");
  JTextField txtName = new JTextField(" John Smith ");
  JTextField txtAddress = new JTextField("                                  ");
  JTextField txtQuantity = new JTextField("0");
  JTextArea txaCurrentPurchase = new JTextArea(10,50);
  JTextArea txaPurchase = new JTextArea(10,50);
  JCheckBox chkEngrave = new JCheckBox(" Engrave");
  JButton btnAddToShoppingCart = new JButton(" Add to Shopping Cart ");
  JButton btnPurchase = new JButton(" Purchase ");
  JPanel pnlApplet = new JPanel();//Panel for Applet
  JPanel pnlMain = new JPanel(); //Panel for Content
  Font  fntMain = new Font("Arial",Font.BOLD,12);

  public void init()
  {
    pnlMain.add(DesignLayout());
    pnlApplet.add(pnlMain);
  }
  public void actionPerformed(ActionEvent action)
  {
  }
  public void DesignLayout()
  {
  // Sets the Layout Mangers propertys
    GridBagLayout gridbag = new GridBagLayout();
    GridBagConstraints constraints = new GridBagConstraints();
    setLayout(gridbag);
    constraints.insets = new Insets(5,2,5,2);
    constraints.fill = GridBagConstraints.NONE;

    //Adds Label(lblTitle) to 0,0
    constraints.gridx = 0;
    constraints.gridy = 0;
    constraints.anchor = GridBagConstraints.EAST;
    gridbag.setConstraints(lblTitle,constraints);
    lblTitle.setForeground(Color.orange);
    add(lblTitle);
  }
}

but that didnt work ?

pnlMain.add(DesignLayout());

Since DesignLayout returns void this can't work.

Ok Thanks
