Reduce Spaces in a GridLayout Java Swing

Question

Good day, please would like to know how to reduce the spaces between the labels and the Textboxes in this picture below and also how to create some spaces between the labels and the frame.Thank you.

My code for this:

private void initUI(JFrame parent) {
    // private void initUI() {
   myPanel = new JPanel(new GridLayout(3,2,1,1));
   buttons_panel = new JPanel(new FlowLayout());

   username_label = new JLabel("Username: ");
   password_label = new JLabel("Password: ");
   username = new JTextField(20);
   password = new JPasswordField(20);

   ok = new JButton("Ok");
   ok.addActionListener(new ActionListener() {

        public void actionPerformed(ActionEvent e) {

        }
    });

    cancel = new JButton("Cancel");
    cancel.addActionListener(new ActionListener() {

        public void actionPerformed(ActionEvent e) {
           dispose();
        }
    });

    myPanel.add(username_label);
    myPanel.add(username);
    myPanel.add(password_label);
    myPanel.add(password);

    buttons_panel.add(ok);
    buttons_panel.add(cancel);

    getContentPane().add(myPanel, BorderLayout.CENTER);
    getContentPane().add(buttons_panel, BorderLayout.PAGE_END);

    pack();
    setResizable(false);
    setLocationRelativeTo(parent);
}

Should i be using GridBagLayout for this instead?..
