wxWindows can be used with threads; but I don't know
how wxPerl will interact with Perl fork emulation, since
I never used it.

Don't use fork? Really: what are you trying to achieve?
I know this does not help you much...

An example of what? I don't understand the question,
so I can't answer.. 
If it is threading, there is no OS-indipendent way:
fork() is inherently not portable, and perl threads are
really stable only on 5.8.0-to-be, AFAIK

fork() is the Un*x way for "threading"

really?
can you provide an example that works os independent?

but i'm always happy to learn!
