I don't know anything about Kylix: I think it's silly to try and sell a
proprietary wrapping of Qt for Linux, since Qt itself is ultra-cool and
fun to use, and _free_ on Linux... I mean, Borland can tell you not to use Qt
except via CLX, but what does that mean when there's a Qt development package
for _every_ distribution under the sun?

As for BlackAdder, the Qt library is wrapped in Python, but using it from
Python is about the same as using it from C++. The GUI designs you
produce with BlackAdder (.ui XML files), you can easily convert to C++
using uic - which comes with Qt, and is free for Linux. The very same C++ source
code that uic on Linux generates, you can compile on Windows.

However, on Windows, you cannot create C++ apps with the Qt library that
comes with BlackAdder, because of the lack of header files. You can only
create Python apps with it. There's a serious differnce in price between
BlackAdder and Qt for Windows - about $1100,-.
