This should get you going.

class TestDialog extends JDialog {

    private JButton okButton = new JButton(new AbstractAction("ok") {
        public void actionPerformed(ActionEvent e) {
            System.err.println("User clicked ok");
            // SHOW THE PREVIEW...
            setVisible(false);
        }
    });
    private JButton cancelButton = new JButton(new AbstractAction("cancel") {
        public void actionPerformed(ActionEvent e) {
            System.err.println("User clicked cancel");
            setVisible(false);
        }
    });

    private JTextField nameField = new JTextField(20);
    private JTextField surnameField = new JTextField();
    private JTextField addr1Field = new JTextField();
    private JTextField addr2Field = new JTextField();
    private JComboBox sizes = new JComboBox(new String[] { "small", "large" });

    public TestDialog(JFrame frame, boolean modal, String myMessage) {
        super(frame, "Envelope addressing", modal);

        JPanel mainPanel = new JPanel();
        mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));
        getContentPane().add(mainPanel);

        JPanel addrPanel = new JPanel(new GridLayout(0, 1));
        addrPanel.setBorder(BorderFactory.createTitledBorder("Receiver"));
        addrPanel.add(new JLabel("Name"));
        addrPanel.add(nameField);
        addrPanel.add(new JLabel("Surname"));
        addrPanel.add(surnameField);
        addrPanel.add(new JLabel("Address 1"));
        addrPanel.add(addr1Field);
        addrPanel.add(new JLabel("Address 2"));
        addrPanel.add(addr2Field);
        mainPanel.add(addrPanel);

        mainPanel.add(new JLabel(" "));

        mainPanel.add(sizes);
        JPanel buttons = new JPanel(new FlowLayout());
        buttons.add(okButton);
        buttons.add(cancelButton);

        mainPanel.add(buttons);

        pack();
        setLocationRelativeTo(frame);
        setVisible(true);
    }


    public String getAddr1() {
        return addr1Field.getText();
    }

    // ...
}

Result:
