Try this
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.text.*;
public class SOSTester extends JFrame {
     public SOSTester() {
          JFrame thisFrame = new JFrame("Testing");
          Container thisCont = thisFrame.getContentPane();
          thisCont.setLayout(new BorderLayout(5,5));
          //// Start Testing
          String[] testList1 = new String[]{"AB","CD","EF"};
          JComboBox jcb = new JComboBox(testList1);
          jcb.setRenderer(new myRen());
          thisCont.add(jcb);
          //// End Testing
          thisFrame.pack();
          thisFrame.setBounds(200,200,400,50);
          thisFrame.setVisible(true);          
     public static void main(String args[]) { new SOSTester();}
class myRen extends JPanel implements ListCellRenderer
     JPanel testPanel = null;
     //JPanel thisPanel = null;
     JLabel text1 = null;
     JLabel text2 = null;
     myRen()
          text1 = new JLabel("",10);
          text2 = new JLabel("",10);
          testPanel = new JPanel();
          testPanel.setLayout(new GridLayout(1,2));
          //testPanel.setLayout(null);
          testPanel.add(text1);
          testPanel.add(text2);
          //thisPanel = new JPanel(new BorderLayout(0,0));
          //thisPanel.add(testPanel, BorderLayout.CENTER);
     public Component getListCellRendererComponent(JList list, Object value, int idx, boolean isSel, boolean hasFocus)
          if (value!=null)
               text1.setText(((String)value).substring(0,1));
               text2.setText(((String)value).substring(1,2));
               //text1.setBounds(5,0,20,25);
               //text2.setBounds(25,0,20,25);
          testPanel.setBackground((isSel)?list.getSelectionBackground():list.getBackground());
          testPanel.setForeground((isSel)?list.getSelectionForeground():list.getForeground());
          //testPanel.setSize(30,30);
          return testPanel;
}
