how to make some specific widths and heights and some auto with jframes - Java

Question

I wanna make a jframe that looks something like this:

As shown on image, I wanna have right side panel to have width of 200px and bottom panel height of 80px, then everything else to be auto, as I want the window to be resizable.

Could someone please help me to achieve this? I've been trying with gridLayout, BorderLayout and others. I've seen something with insets, but can't figure it out.

I believe this should do the trick.

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class MainFrame extends JFrame {
    public static void main(String[] args) {
        MainFrame frame = new MainFrame();
        JPanel centerWrapper = new JPanel();        

        JPanel center = new JPanel();
        center.setBackground(Color.BLUE);

        JPanel right = new JPanel();
        right.setBackground(Color.CYAN);
        right.setPreferredSize(new Dimension(200, 10));

        centerWrapper.setLayout(new BorderLayout());
        centerWrapper.add(center, BorderLayout.CENTER);
        centerWrapper.add(right, BorderLayout.EAST);

        JPanel bottom = new JPanel();        
        bottom.setPreferredSize(new Dimension(640, 200));
        bottom.setBackground(Color.GREEN);

        frame.setLayout(new BorderLayout());
        frame.add(centerWrapper, BorderLayout.CENTER);
        frame.add(bottom, BorderLayout.SOUTH);

        // you can now use center, right and bottom

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(640, 480);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}
