Make dynamic layout Java Swing

Question

How can I achieve this effect using Swing:

When resizing of the width the JFrame, I want the blue JPanel to be fluid and the green JPanel to be fixed. When resizing the height, I want both to be fixed. I also want the blue JPanel to not have less than some predefined width and the green JPanel to never move under the blue JPanel, remaining always on the right.

The MigLayout was designed for these situations: http://www.miglayout.com/

JPanel panel = new JPanel();
panel.setLayout(new MigLayout(
    "", 
    "[grow][200px]", // Column constraints
    "[100px]"        // Row constraints
));
