Answer 1

You should have a new class that extends Jframe called something appropriate (MainWindow maybe) that gets created when the user enters the correct password, so probably in the eventListener code for the button

if (usernameAndPasswordCorrect()) {
    loginWindow.setVisible(false);
    loginWindow.dispose();
    MainWindow w = new MainWindow();
    w.setVisible(true);
}
else {
    JOptionPane.showMessageDialog(loginWindow, "Incorrect login information. Try again.");
}

Or something like that.
