Contents of JFrame convert to JPanel

I have this code in which a Gantt Chart will be shown on another JFrame, other than the main UI frame. Is there any way such that the drawn Graphics here will be shown on a JPanel on the main UI frame? 

chart= new JFrame();
final ArrayList<Task> tasks = taskList;
final int ET = processET;
chart.setSize(300, 300);
chart.setContentPane(new JPanel(){
    public void paint(Graphics g){
      for(int j=0;j &lt tasks.size();j++)
        {
            int ST = 0;
            if(j!= tasks.size()-1) ST = tasks.get(j + 1).getStartTime();
            else ST = ET;
            int Product = ST * 20;    
            g.drawRect(50,50,Product,30);
            g.drawString("p"+tasks.get(j).getPID(),(55+(tasks.get(j).getStartTime()*20)),70);
            g.drawString(""+tasks.get(j).getStartTime(),    (50+(tasks.get(j).getStartTime()*20)),100);
        }
        g.drawString(""+ET,50+(ET*20),100);
        }
    });
    chart.pack();
    chart.setLocationRelativeTo(null);
    chart.setVisible(true);

I tried this code so that it would put it on a JPanel, but obviously it did not work, hence this inquiry. Please help and thanks :)

 panel_2 = new JPanel(){ "same thing" };   
 panel.add(panel_2);

There are a number of ways. See this answer for details. I'm thinking either a CardLayout or JTabbedPane might be the easiest, given that code is already rendered in a JPanel (that is currently added to a frame for display).
