I'm having a problem with in merging time and button together...

I can't get the button show in the JPanel.

This is my code:

import java.awt.Color;
import java.awt.Font;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public final class Date_Time extends JFrame{
    private static final long serialVersionUID = 1L;
    private JPanel show_date_time = new JPanel();
    private JLabel time = new JLabel("Time:");
    private JLabel show_time = new JLabel("Show Time");

    DateFormat dateFormat2 = new SimpleDateFormat("h:mm:ss a");
    java.util.Date date2;
    private JLabel label;
    private JPanel panel;

     public Date_Time(){
        this.setSize(300, 300);
        this.setResizable(false);
        getContentPane().add(Show_Time_date());
     }
     private JButton button1 = new JButton();
     private JFrame frame1 = new JFrame();
    public JPanel Show_Time_date(){
        frame1.add(show_date_time);
        show_date_time.setBackground(Color.ORANGE);
        frame1.add(button1);
        getShow_date_time().setLayout(null);
        Font f;
        f = new Font("SansSerif", Font.PLAIN, 15);
        getTime().setBounds(0,250,400,30);
        getTime().setFont(f);
        getShow_date_time().add(getTime());
        setShow_time(new JLabel(""));
        updateDateTime();
        getShow_time().setBounds(37,250,400,30);
        getShow_time().setFont(f);
        getShow_date_time().add(getShow_time());
        return getShow_date_time();

    }

    public static void main(String[] args) {
        Date_Time Main_win=new Date_Time();
        Main_win.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Main_win.setVisible(true);
    }

    public void updateDateTime()
    {

            while(true)
                {
                date2 = new java.util.Date();
                String dateTime = dateFormat2.format(date2);
                    getShow_time().setText(dateTime);
                    getShow_time().updateUI();

                }
            }
        });
    th.start();
    }

    /**

     */

    }
