Java layout manager.

Hello all,

 I have this lovely piece of code that I have been working on that I want to add 361 equally sized boxes (panels). In other words a 19 rows by 19 columns but I dont want to use a jTable or anything like that. I tried to use Jbuilder 7 to help with the layout and on the button click. You'll see my attempt to create this grid. I need each panel to touch each other at the edges and all of them to grow in the same way if the screen is enlarged or shrunk. Any ideas on how I should do this. Is the layout I chose no good for this? Code example using this stuff would be great. Thanks.
