Insert a JFrame into a JPanel or something

Is there a way that I do what I have in my JFrame but inside a Panel or another structure instead?

I'll show you my code:

import java.awt.GridBagConstraints;

import java.awt.GridBagLayout;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.IOException;

import javax.swing.JFrame;

import javax.swing.SwingUtilities;

import ptolemy.plot.Plot;

//////////////////////////////////////////////////////////////////////////

//// TwoPlotExample

public class TwoPlotExampleinvento extends JFrame {

TwoPlotExampleinvento() {

// Instantiate the two plots.

Plot leftPlot = new Plot();

Plot rightPlot = new Plot();

// Set the size of the toplevel window.

setSize(400, 500);

leftPlot.setSize(350, 200);

leftPlot.setButtons(true);

leftPlot.setTitle("Se馻l en el tiempo");

leftPlot.setXLabel("Tiempo (segundos)");

leftPlot.setYLabel("Amplitud");

leftPlot.setMarksStyle("none");

leftPlot.setImpulses(true,1);

for (double i = -4; i <= 50; i=i+1) {

leftPlot.addPoint(1, i, 5 * Math.sin((Math.PI * i) / 20), false);

leftPlot.addPoint(2, i, 10 * Math.cos((Math.PI * i) / 25), true);

}

int T=5;

for (double i = -4; i <= T; i=i+1){

leftPlot.addPoint(4,i,2*i+1,true);

}

rightPlot.setButtons(true);rightPlot.setSize(350, 200);

for (int i = -4; i <= 50; i++) {

rightPlot.addPoint(0, i, 5 * Math.cos((Math.PI * i) / 20), true);

}

rightPlot.setTitle("Espectro de Frecuencia");

rightPlot.setXLabel("Frecuencia (Hz)");

rightPlot.setYLabel("Amplitud");

// Layout the two plots

GridBagLayout gridbag = new GridBagLayout();

GridBagConstraints c = new GridBagConstraints();

getContentPane().setLayout(gridbag);

// Handle the leftPlot

c.gridx = 0;

c.gridy = 0;

c.gridwidth = 1;

gridbag.setConstraints(leftPlot, c);

getContentPane().add(leftPlot);

// Handle the rightPlot

c.gridx = 0;

c.gridy = 1;

c.gridwidth = 1;

//c.fill = GridBagConstraints.BOTH;//Creo que esto obliga a que los graficos ocupen toda la pantalla

c.weightx = 1.0;

c.weighty = 1.0;

gridbag.setConstraints(rightPlot, c);

getContentPane().add(rightPlot);

setVisible(true);

}

/** main method called in a standalone java application.

* We simple instantiate this class, most of the work

* happens in the constructor.

*/

[b] public static void main(String[] args) {

// We execute everything in the Swing Event Thread, see

// the comment

Runnable doAction = new Runnable() {

public void run() {

new TwoPlotExampleinvento();

}

};[/b]

SwingUtilities.invokeLater(doAction);

}

}
