You can check the classic publication:
Exploiting Windows NT 4.0 Buffer Overruns (A Case Study: RASMAN.EXE)
http://www.ngssoftware.com/papers/ntbufferoverflow.html
A lot of good tips on this topic can be also found in Shellcoder's handbook if you need introduction to more advance topics on this platform. Also take a look at kungfoo project and MetaSploit for universal shellcodes.
Remember that you don't call Win32 API with syscall (int 80h) like in Linux but you need to have correct address to issue call instruction.
Just my 2 cents
