How to display a webpage in java

I know some already know how to, but I've seen the code and I can't get it to display on the Frame. I tested with lots of different codes but I can't simply get the EditorFrame to show up in the JFrame. (I'm a noob in Java, any help or advices is really appreciated!)

public class MainGui{

private JFrame frame;
/**
 * Launch the application.
 */

public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                MainGui window = new MainGui();
                window.frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

/**
 * Create the application.
 * @return 
 */
public MainGui() {
    initialize();
}

/**
 * Initialize the contents of the frame.
 */
private void initialize() {
    frame = new JFrame();
    frame.setBounds(100, 100, 1150, 700);
    frame.setTitle("Game Launcher");
    Image icono = Toolkit.getDefaultToolkit().getImage("ic.png");
    frame.setIconImage(icono);  
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.getContentPane().setLayout(null);

    JLabel lblCurrentUserCyberdg = new JLabel("Current User: Cyberdg_");
    lblCurrentUserCyberdg.setFont(new Font("Segoe UI", Font.PLAIN, 16));
    lblCurrentUserCyberdg.setBounds(10, 11, 172, 22);
    frame.getContentPane().add(lblCurrentUserCyberdg);

    JLabel lblLauncherVersion = new JLabel("Launcher Version: 0.0.1-pre1");
    lblLauncherVersion.setFont(new Font("Segoe UI", Font.PLAIN, 16));
    lblLauncherVersion.setBounds(10, 44, 172, 22);
    frame.getContentPane().add(lblLauncherVersion);

    JLabel lblCurrentlyThereIs = new JLabel("Authentication System: Off");
    lblCurrentlyThereIs.setFont(new Font("Segoe UI", Font.PLAIN, 16));
    lblCurrentlyThereIs.setBounds(10, 77, 242, 22);
    frame.getContentPane().add(lblCurrentlyThereIs);

    lblVersionEditor.setFont(new Font("Segoe UI", Font.BOLD, 16));

    JLabel lblGameVersion = new JLabel("Game Version: 1.8.3");
    lblGameVersion.setFont(new Font("Segoe UI", Font.PLAIN, 16));
    lblGameVersion.setBounds(10, 219, 143, 22);
    frame.getContentPane().add(lblGameVersion);

    JLabel lblWelcomeCyberdgReady = new JLabel("          Welcome, Cyberdg_! ");
    lblWelcomeCyberdgReady.setFont(new Font("Segoe UI", Font.PLAIN, 16));
    lblWelcomeCyberdgReady.setBounds(10, 493, 242, 22);
    frame.getContentPane().add(lblWelcomeCyberdgReady);

    Scrollbar scrollbar = new Scrollbar();
    scrollbar.setBackground(Color.WHITE);
    scrollbar.setBounds(1117, 0, 17, 641);
    frame.getContentPane().add(scrollbar);

    JButton btnNewButton = new JButton("Play");
    btnNewButton.setFont(new Font("Segoe UI", Font.PLAIN, 16));
    btnNewButton.setBounds(10, 555, 242, 75);
    frame.getContentPane().add(btnNewButton);

    JMenuBar menuBar = new JMenuBar();
    frame.setJMenuBar(menuBar);

    JMenu mnAbout = new JMenu("About");
    menuBar.add(mnAbout);

    JMenuItem mntmLauncherVersion = new JMenuItem("Launcher Version");
    mnAbout.add(mntmLauncherVersion);

    JMenuItem mntmDevInfo = new JMenuItem("Dev Info");
    mnAbout.add(mntmDevInfo);
}
