Steam GCF launcher


I coded many things but never used .dll files external functions... Now i want to code steam launcher and have problemz with it... What i need to load that functions from some emulator ??

I think need some steam.h files etc...

Tell me everythink u know about it :)
I've never used an emulator + the fact I hate c++. Like, I really hate it lol. If you could convert it to, I could write something better than steamemu :D.
Ok no problem i'll digg up as much as i can but it's really hard to read half of a code that TinyLauncher has in his source... and i can't compile it :/
