"intToWord32" and friends have been deprecated more than 3 years ago, and
recent Haskell platforms have dropped the support for it completely. You
can easily use the more general "fromIntegral" as a replacement.

Yep, it's only an internal function in that module.

The "primitive" keyword is used for Hugs internals only. It means that the
runtime system has a C function registered with the given name. Think of
"primitive" as the glue between C and Haskell. It has got nothing to do
with any filenames.

It really depends on your GUI needs,

    http://haskell.org/libraries/#guigs

offers a lot options in this area.
