GUI, JFrame, JPanel, ActionListener, simple multi-class applications

Question

My assignment calls for:
"Create a Frame class"
"Create a Panel class which implements ActionListener. Add JLabels, JTextFields, JButtons to the panel"
most of this is pretty straight forward right out of GUI examples from my textbook
but I don't have much experience with running multi-class programs, and this one is a bit more complicated b.c we have to use implement and possibly extend modifiers, which are new to me
any thoughts?

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TestX extends JFrame {
MyPanel pnl;
public TestX() {
super();
pnl = new MyPanel();
getContentPane().add(pnl);
setDefaultCloseOperation(EXIT_ON_CLOSE);
pack();
setVisible(true);
class MyPanel extends JPanel implements ActionListener
private JLabel lbl;
private JTextField txt;
private JButton btn;
public MyPanel() {
super();
lbl = new JLabel();
txt = new JTextField();
btn = new JButton("btn");
btn.addActionListener(this);
add(lbl);
add(txt);
add(btn);
public void actionPerformed(ActionEvent e) {
txt.setText("Clicked");
