I posted a simple solution to this a few weeks ago.  I don't remember if 
it was you who posted or not but nothing was heard out of the original 
poster.

The solution basically to not use multiple JPanels but to put all of the 
fields in one panel, add some extra padding where you want the borders 
and then to put the border around the bounds of the components.

I'll see if I can find it again.
