Date/Calendar picker-- please help

Question

Hello
Would someone please help me out? I am trying to get the date picker from the demo below.
http://www.toedter.com/en/jcalendar/demo.html
However, I have a JButton in my short program. Once I click on the JButton, I need the calendar to show just as it does w/ the first icon in the demo.
According to the documentation calling JDateChooser() would make the calendar visible. I have installed the package on my machine.
In my code when I click on the button, nothing happens.
import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextField;
//import com.toedter.calendar.JDateChooser;
public class program1 extends JFrame
  private static final long serialVersionUID = 1;
  static JFrame frame = new JFrame();
  static JButton B1 = null;
  static JTextField tfDateTime = new JTextField(30);
  public static void main(String args[])
    frame.setTitle("JCalendar");
    JPanel mainPanel = new JPanel();
    JScrollPane scrollPane = new JScrollPane(mainPanel);
    //ImageIcon img = Utility.loadIconByName("/images/JCalendarColor32.gif");
    B1 = new JButton();
    mainPanel.setLayout(new GridBagLayout());
    GridBagConstraints a = new GridBagConstraints();
    a.insets = new Insets(0, 10, 8, 0);               //1. Date/Time label and TextField
    a.gridx = 0;
    a.gridy = 1;
    a.anchor = GridBagConstraints.WEST;
    mainPanel.add(new JLabel("1. Date/Time:"), a);
    a.gridx = 1;                           
    mainPanel.add(tfDateTime, a);
    a.gridx = 2;         
    B1.addActionListener(new java.awt.event.ActionListener()
      public void actionPerformed(final java.awt.event.ActionEvent e)
        JDateChooser D = new JDateChooser();
    mainPanel.add(B1, a);
    frame.add(scrollPane);
    frame.setSize(new Dimension(700,200));
    frame.setLocation(200,200);
    frame.setVisible(true);
}I am reading the doc and the JDateChooser() and still can't figure out how to make this work.
How can I get the calendar to show when i click on the JButton (B1) in my code. Would someone please please help me out ?
Thanks in advance
