Help With GUI

[Ghost12345]

Hi, sorry ima noob... but can someone help me with adding a List on the right side of my chat window? Currently doing an ISU for my Java course.. Thanks.

package components;

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

public class ChatWindow extends JPanel implements ActionListener {
protected JTextField textField;
protected JTextArea textArea;
private final static String newline = "\n";

public ChatWindow() {
super(new GridBagLayout());

textArea = new JTextArea(25, 60);
textArea.setEditable(false);
JScrollPane scrollPane = new JScrollPane(textArea,
JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);

textField = new JTextField(20);
textField.addActionListener(this);


GridBagConstraints c = new GridBagConstraints();
c.gridwidth = GridBagConstraints.REMAINDER;

c.fill = GridBagConstraints.BOTH;
c.weightx = 1.0;
c.weighty = 1.0;
add(scrollPane, c);

c.fill = GridBagConstraints.HORIZONTAL;
add(textField, c);

}

public void actionPerformed(ActionEvent evt) {
String text = textField.getText();
textArea.append(text + newline);
textField.selectAll();

textArea.setCaretPosition(textArea.getDocument().getLength());
}

/**
* Create the GUI and show it.
*/
private static void createAndShowGUI() {
JFrame frame = new JFrame("TextDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.add(new TextDemo());

frame.pack();
frame.setVisible(true);
}

public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}
