Sorry, just now saw this. I've only used Python on appengine, so I can't really comment on your particular experience. It supports Java, and it's super-important to realize that you won't be working with a database, you'll be working with a dataSTORE (which is comprised of hash tables, sorta). give it a shot. if you hate it, quit!
