I've done this with CCL two different ways:

1. Use CCL's FFI to talk to the Win32 APIs.

2. Use LTK. (http://peter-herth.de/ltk/)

LTK is far and away the easier way to go. Even if it's not suitable in the end, I'd start with it, because you can pretty easily get enough of your UI built to figure out what you really want to do with the Win32 APIs. If you're lucky, LTK is good enough, and you don't have to go through the whole rigamarole of learning Win32.

Another alternative is to use Lispworks, which has a pretty comprehensive platform-independent GUI library, but it's not cheap, and it's not CCL.
