This question pops up from time to time, and unless there is something new
in NB 3.5 that I haven't noticed, the answer is still `no'. JDK 1.4.x has
new support for Swing serialization that will produce an XML-based external
representation of the UI, and the few times I have looked inside a .form
file it was also XML-based, but differences between them still probably
exist. Printing the UI source code and rebuilding it from scratch using the
source as a guide may be your best bet.
