I think this is a major task, and I might even consider it to be less of
a hassle to rewrite the application (keep as much of it as you can, but
move as much as you can to GTK or QTEmbedded and the C++ STL)

I never worked with Wind/U, but if the have a working Linux/ARM implementation
you might have luck

It's basically an Debinan GNU/Linux system running on an ARM processor
if you can port it to Linux on an i386 you're half way there, than you
have to get it working on an ARM processor.

The same as for any linux with 32MB of RAM (about 24MB of free RAM, 32bits,
a configurateable ammound of file handles (IIRC 1024 to start with))

No, most likely not, as it's an ARM CPU you'd have to emulate an i386 to
run Windows Applications on it.

No, but you could use VMware or VirtalPC to run a Debian GNU/Linux on
i386. This is as close to an iPaq you will get (with an i386 processor)

Your biggest problem will be tha fact, that the iPaq uses an ARM
processor.
