Yeah, it's a judgment call.  If you're using a handfull of functions
from the Win32 API, then creating your own domain-specific wrapper
around them can be easy.  If you need to wrap hundreds of API calls
from Win32 then you'll want something more automated.

On the flip side, sometimes you end up with better architecture as a
side benefit of creating the insulting domain specific layer.  You end
up with interfaces that more directly describe the specific services
needed by your application.
