Fixing resizing issue in BorderLayout. Either the buttons move or dont show - border-layout

Question

I need to make a GUI interface (using BorderLayout) that looks like the image attached.(http://i.imgur.com/wRN4vlH.jpg)
the issue is that I am not allowed to restrict resizing and the buttons can not move to another row. I have the code working to display the proper image I dont know how to make it show the buttons without resizing and without the buttons moving. Any suggestions would be truly helpful
import java.awt.*;
import javax.swing.*;
class MyComponents extends JFrame{
MyComponents (String title){
JFrame frame = new JFrame(title);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
BorderLayout layout = new BorderLayout(2,3);
frame.setLayout(layout);
JPanel northPanel = new JPanel();
//JPanel westPanel = new JPanel();
JPanel centerPanel = new JPanel();
//JPanel eastPanel = new JPanel();
JTextField Text = new JTextField();
northPanel.add(new JLabel("Current Value:"));
northPanel.add(Text);
Text.setPreferredSize(new Dimension(50,24));
centerPanel.add(new JButton("+"));
centerPanel.add(new JButton("-"));
centerPanel.add(new JButton("Reset"));
centerPanel.add(new JButton("Quit"));
frame.add(northPanel, BorderLayout.NORTH);
frame.add(centerPanel, BorderLayout.CENTER);
frame.setVisible(true);
}
}
public class Homework7b {
public static void main (String [] args)
{
MyComponents Homework7b = new MyComponents("Part 02 Using getSource");
}
}
