Adding two BufferedImages together?

Question

Is there anyway to "for lack of a better word add two bufferedImages together?
For example if I have a JLabel with an ImageIcon thats a red square 32 x 32 pixels and another JLabel with an ImageIocn thats a green square also 32 x 32 pixels. Can I create a new ImageIcon thats 64 x 32 pixels that is the red square and green square together?
Something like new BufferedImage(image1, image2,  concanate_xaxis);Thanks,
Cathal.

Ive tryed to impliment your above suggestion camickr, but all I can seem to get as output is a black image.
Heres some code that demonstrates my problem.
Once the following code is compiled and run an image is created using all of the JLabels ImageIcons from the JFrame and its saved into a file at "C:/Image.png". Obviously this would have to be changed for testing purposes depending on ones OS and Drive letter preferences.
import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.BufferedImage;
import java.io.*;
import javax.imageio.*;
public class Example2
       static JFrame frame;
       static JLayeredPane layeredPane;
       public static void main(String[] args)
              frame = new JFrame("Example");
              frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
              frame.setResizable(false);
              frame.setSize(320, 320);
              frame.setLocationRelativeTo(null);
              frame.getContentPane().setLayout(null);
              layeredPane = new JLayeredPane();
              layeredPane.setOpaque(true);
              layeredPane.setLayout(null);
              layeredPane.setBounds(0, 0, 320, 320);
              frame.setContentPane(layeredPane);
              for(int i = 0; i < 32; i ++)
                      for(int j = 0; j < 32; j ++)
                           JLabel label = new JLabel(new ImageIcon("images/grass.gif"));
                           layeredPane.add(label, new Integer(0));
                           label.setBounds(i * 32, j * 32, 32, 32);
              frame.setVisible(true);
              createAndSaveImage();
       public static void createAndSaveImage()
              BufferedImage image = new BufferedImage(320, 320, BufferedImage.TYPE_INT_RGB);
              Component[] components = layeredPane.getComponentsInLayer(0);
              int count = 0;
              for(int i = 0; i < 32; i ++)
                      for(int j = 0; j < 32; j ++)
                              JLabel label = (JLabel)components[count];
                              label.getGraphics().drawImage(image, i, j, 32, 32, null);
                              count ++;
              try
                    ImageIO.write(image, "png", new File("C:/Image.png"));
              catch(Exception exexe)
