If the library you want to use is already available under COM, I agree with 
Karl M Syring that Haskell->COM tools (i.e., H/Direct) are the way to go.

If they are available as normal C libraries, I'd recommend using either the 
foreign function interface (ffi) 

  http://www.cse.unsw.edu.au/~chak/haskell/ffi/

or one of the tools that sits atop the foreign function interface.  There is a 
very preliminary and slightly dated overview of all the tools here:

The best place to ask for information is on the ffi mailing list 
(ffi@haskell.org).  In general, the more specific your question, the better 
the answer is likely to be.

Hope this helps.
