Swing & all GUI toolkit work takes a while to get your head around, especially if you have only worked on the backend, and there is way too much to put in a few emails. One idea is that Swing (as any GUI toolkit) is fundamentally single threaded.
The first thing that strikes me is "setFocus()". More typically you would call a "request-Focus()" type method, and even that would be put in Swing's Event Dispatch Thread (EDT) with an "invokeLater" call. I've hacked around in Swing for 10+ years - but I'm far from an expert. Perhaps stop trying to control the focus (try to leave that to Swing where possible). If you are playing / learning it might be good to follow an existing start-to-finish tutorial. Just some clues, so YMMV.
