Resize JToolBar from all the cornors

Question

I added buttons to JToolbar. When resize form any cornor it should resize. Added tools should also move in row and column wise to set with size. I am also pasting the code below. How to do this?
package com;
import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
public class Design {
     private void initComponents() {
          toolbar = new JToolBar();
          docToolbar = new JFrame();
          docToolbar.setAlwaysOnTop(true);
     toolbar.setMargin(new Insets(0,0,0,0));
          JButton image = new JButton();
          image.setIcon(new ImageIcon("d:\\icons\\a.png"));
          JButton cut = new JButton();
          cut.setIcon(new ImageIcon("d:\\icons\\b.png"));
          JButton email = new JButton();
          email.setIcon(new ImageIcon("d:\\icons\\c.png"));
          JButton menu = new JButton();
          menu.setIcon(new ImageIcon("d:\\icons\\d.png"));
          toolbar.add(image);
          toolbar.add(cut);
          toolbar.add(email);
          toolbar.add(menu);
          documentToolbar.getContentPane().add(toolbar);
     docToolbar.setUndecorated(true);
     docToolbar.pack();
     docToolbar.setVisible(true);
     docToolbar.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
     public static void main(String args[]){
          Design ds= new Design();
          ds.initComponents();
     private JToolBar toolbar;
     JFrame doctToolbar;
     JToggleButton[] toolBarButtons;
     JButton image;
     JButton cut;
     JButton email;
