JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);

if (response == JOptionPane.OK_OPTION) {
String name = login.getName();
String pWord = login.getPassword();

if (name.equals("Fubar") && pWord.equals("Snafu")) {
JFrame frame = new JFrame("Main Application");
JLabel label = new JLabel("Main Application", SwingConstants.CENTER);
label.setPreferredSize(new Dimension(400, 300));
frame.getContentPane().add(label);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}

String msg = "Incorrect name and password. \n(try Fubar and Snafu)";
JOptionPane.showMessageDialog(null, msg);

class LoginPanel extends JPanel {
private JTextField nameField = new JTextField(10);
private JPasswordField passwordField = new JPasswordField(10);

public LoginPanel() {
setLayout(new GridLayout(2, 2, 5, 5)); // change to GridBagLayout later

Would you like to have a seat, kick your shoes off and help yourself to some doughnuts while we do your work for you?

Sorry but it doesn't work that way as we're volunteers and not here for this purpose. I suggest that you look for the tutorial for what you're trying to do, and then if you get stuck show us your code (with code tags so we can read it), your errors and perhaps we'll be able to help.
