import java.awt.Container;
import java.awt.GridLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

public class LoginGui extends JFrame implements ActionListener
{
public static final int WIDTH = 200;
public static final int HEIGHT = 100;

public static void main(String args[])
{
LoginGui gui = new LoginGui();
gui.setVisible(true);
}

public LoginGui()
{
super("Account Login");
setSize(WIDTH, HEIGHT);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

Container c = getContentPane();
c.setLayout(new GridLayout(3,2));

JLabel label1 = new JLabel("User Name:");
JLabel label2 = new JLabel("Password:");
JTextField userName = new JTextField(20);
JTextField password = new JTextField(20);
JButton login = new JButton("Login");

c.add(label1);
c.add(userName);
c.add(label2);
c.add(password);
c.add(login);
login.addActionListener(this);
}

public void actionPerformed(ActionEvent e)
{
JOptionPane.showMessageDialog(null, "Account successfully created!");
