Resize the components of the frame in full-screen mode

Question

I want my frame components to be always adjusted in the screen, regardless of screen size. I draw the frame in my Laptop (small screen) and when I run my application in another machine (jar file) with a big screen the frame components doesn't re-size!

How I can make my frame resize it's components when I put the frame in full-screen mode in any machine?

See Laying Out Components Within a Container.

OK, I hacked out some code in the shape of your original GUI that uses layouts and will resize. Since I was not clear on where the extra height should be assigned, I gave it to the text area. Colors, font size etc. are left as an exercise for the user.
