No, Qt exists in non-GPL versions for win32 and Mac. The Java binding
will most likely just work there, too.

FUD.

Because of bytecode verification and all that.

backend (Intershop Enfinity - eCommerce engine, EJB, Oracle, XML,
CORBA).

Oracle developers apparently have no clue about 1) Writing installers.
2) Writing client-side Java that doesn't look crappy and actually works.
