In the next few days we'll release GHC 5.02.
The Windows version of that will not require any version of cygwin;
it comes complete, and you don't need to install anything else to make
it work. (Nor does it mind if you have some version of cygwin
installed,

As a general question (and forgive my ignorance): are the various ffi's
implemented using something like `dlopen' or are they done by actually
putting suitable stubs into the Haskell generated C-code which then gets
compiled by the C compiler as part of the overall haskell compilation?

Out of curiosity, how does GTK+ compare with Fruit?
GTK+ has a C API heavily based on call backs and mutable
state. Thus, the Haskell transcription of that API heavily
relies on the use of the IO monad - as does H98 textual IO.
It seems like it
