Hu, in fact it's the other way around: VST is a C ApI based of a very small set of functions passing "opcodes" arround. It is wrapped with C++ on the plugin side but you can writte C only VST plugins (well, I don't know of any C only VST plugins anyway). DirectX/DirectShow is totaly COM based and thus C++ is almost mandatory. Of course you would be able to use COM objects in C by calling their methods thru the virtual functions table but COM allready being a pain in C++ I wouldn't advise anyone to go for this solution.
MSVCRT is just the equivalent of the gnu libc, most functions are the same and the missing ones can be emulated quite easily with the corresponding set of call to the libc. The main problem would more be the dependency to the Win32 API thru gdi32.dll, user32.dll, kernel32.dll, etc... But all of these are allready well emulated by wine (you woulnd't be able to run word or winamp with wine without it).
