Hello: **My program is below**

I would like my program to have a window that asks whether the amount of "people in party" is correct it would then have a text field for yes enter 1 and no enter 2. But I don't know how do get it correct. Thanks for any help. I'm getting confused with the Pane being from the main Pane add how to add different button/textfield to each.

This will do:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Menu extends JFrame
     private JTextField partyNumField;
     private int        partyNum;
     private JButton    getParty;
     private JLabel     party, companyLogo;
public Menu()
     super("O'Brien Caterer - Where we make good Eats!");
     addWindowListener(new WindowAdapter()
    {     public void windowClosing(WindowEvent ev)
               dispose();     
               System.exit(0);
     Container container = getContentPane();
     JPanel northPanel   = new JPanel();
     northPanel.setLayout(new FlowLayout(FlowLayout.CENTER, 80, 5));
     companyLogo         = new JLabel("Welcome to O'Brien's Caterer's");
     northPanel.add(companyLogo);
     party               = new JLabel("Enter the Total Number in Party Please");
     partyNumField       = new JTextField(5);
     northPanel.add(party);
     northPanel.add(partyNumField);
     getParty            = new JButton("GO - Continue with Order");
     getParty.addActionListener(new ActionListener()
          public void actionPerformed(ActionEvent actionEvent)
               partyNum = Integer.parseInt(partyNumField.getText());
               String a = JOptionPane.showInputDialog(null, "Total Number is party is: " + partyNum
                    + " is this correct?\n\n" + "Enter 1 to continue\n"
                    + "Enter 2 to cancel\n");
     northPanel.add(getParty);
     container.add(northPanel);
     setSize(500,300);
     show();
public static void main(String args[])
     new Menu();
