I suggest you use packer, a GridBagLayout helper, it is much easier to 
use that GridBagLayout on it's own, see:
https://packer.dev.java.net/

BTW: There is some odd behaviour (IMHO bugs) in GridBagLayout, which I 
found using packer, so it is worth trying extra constraints, even if 
they don't make sense.  BoxLayout maybe useful if you get stuck and 
don't have time to experiment.
