Evo ti jedan malecki primer...

Code:

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

import sun.awt.VerticalBagLayout;

public class Forma extends JFrame{
    private static final long serialVersionUID = 5623732470443033149L;
    private static Forma instance = null; // omogućuje da forma bude singleton
    public JPanel prazno = new JPanel(), prazno1 = new JPanel(), prazno2 = new JPanel(), prazno3 = new JPanel(),
                  levaMargina = new JPanel(), desnaMargina=new JPanel(), sadrzaj = new JPanel();
    public JComboBox nesto = new JComboBox(),
                    student  = new JComboBox(),
                    brIndexa = new JComboBox();
    public JButton dodatakD = new JButton("Dugme");
    private Forma() { // singleton forma
        init();
    }
    public static Forma getInstance(){ // singleton forma
        if (null == instance)
            instance = new Forma();
        return instance;
    }
    public void init(){
        setLayout(new BorderLayout());
        setPreferredSize(new Dimension(250,250));

        prazno.setPreferredSize(new Dimension(120,26));
        prazno.add(new JLabel("Nešto:                                                    "));

        nesto.addItem("");
        nesto.addItem("Nešto1");

        prazno2.setPreferredSize(new Dimension(120,26));
        prazno2.add(new JLabel("Broj Indeksa:                               "));
        prazno3.setPreferredSize(new Dimension(120,26));
        student.setPreferredSize(new Dimension(120,26));
        brIndexa.setPreferredSize(new Dimension(120,26));
        dodatakD.setPreferredSize(new Dimension(120,26));
        dodatakD.addActionListener(new KlikDD());

        levaMargina.setPreferredSize(new Dimension(10,26));
        desnaMargina.setPreferredSize(new Dimension(10,26));
        sadrzaj.setPreferredSize(new Dimension(120,180));
        sadrzaj.setLayout(new VerticalBagLayout());

        add(levaMargina,BorderLayout.WEST);
        add(desnaMargina,BorderLayout.EAST);

        sadrzaj.add(prazno);
        sadrzaj.add(stProgram);
        sadrzaj.add(prazno1);
        sadrzaj.add(student);

        sadrzaj.add(prazno3);
        sadrzaj.add(dodatakD);

        add (sadrzaj,BorderLayout.CENTER);

        pack();
        setVidljivost(false);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
    private void setVidljivost(boolean vidljiv){
        student.setEnabled(vidljiv);
        brIndexa.setEnabled(vidljiv);
    }

    private class KlikDD implements ActionListener{
        public void actionPerformed(ActionEvent e) {
                   prazno1.removeAll();
                  prazno1.add(new JLabel("KlikDD:                                              "));
        }
    }
    private class IzborNecega implements ActionListener{
        public void actionPerformed(ActionEvent e) {
            switch (stProgram.getSelectedIndex()){
                case 1:
                                                   case 2:
                case 3:
                case 4:
                case 5:
                case 6:
                case 7:setVidljivost(true);
                          break;
                default:setVidljivost(false);
            }
        }

    }

    public static void main(String args[]){
        Forma dd = Forma.getInstance();
        dd.setVisible(true);
    }
}

Slično kao nesto možeš da konfigurišeš i student i brIndeksa JComboBox-ove.
