I found it because I was looking for the QtC library (C wrapper for Qt)
which I know existed once. I then found out it had been superseded with
Smoke (used by qtruby qnd qtcsharp).

I'm not a CLOS expert neither, but defining classes and methods is not
that complicated. The major problem I had to solve was to find a way to
provide a C++-like method overloading mechanism for methods with
number of parameters (in CLOS, methods with the same name must have a
congruent set of parameters). For the rest, I'm still looking for the
way to integrates constructors, signals and slots.

I've been a KDE developer, so I've always been interested by Qt
Now that it's available as GPL under Windows (with an exsting patch, you
even compile it with MSVC), I wanted to tried it out.

I'll send you the code by private mail, such that you can have a look
(it's ~2MB).
