Not really

I don't have a slightest idea how the code proceeds over those controls. But SaberHawk pointed me to a .exe to .c translator ( boomerang.sourceforge.net - be warned, I've been running it for like 4 hours and it still hasn't finished translating ). I am hoping it creates something useable, cause I don't really have other ideas - spending 10 or 15 minutes disassembling the executable after each internal error just takes too much patience. It would be very interesting to hear Olaf's comments on this, I'll post at his forum.
Edit: bah, boomerang crashed after 8 hours of work...

All it left is a 163 kb txt file with a structured plan of what function calls what, unfinished most probably. I thought my 1700+ XP would be enough for the task :| Damn it.
