Can you show us how it looks?

I'm also waiting for the GtkAda 2.0 as it has propper support for
languages etc...

   Using GTK+ in your own programs

   In order to use the DLLs as distributed in programs you build
   yourself, you must use either gcc-2.95.2 (or later, 2.95.3 certainly
   works, dunno about GCC 3), or Microsoft Visual C++ 5 or 6. With gcc,
   you should use the -mno-cygwin and -fnative-struct flags. Using any
   other gcc setup will not work. (Hint: struct field alignment. Hint 2:
   msvcrt.dll.) If you don't understand what I am talking about, just
   trust me.

   If you are porting a program that uses GTK+ 1.2 on Unix, use GTK+
   1.3.0 on Windows. Don't be afraid of the 1.3 version number, it
   actually is mostly like 1.2.7, API-wise.

   You are expected to be pretty experienced to be able to use GTK+ in
   your own programs. This isn't Visual Basic. Please don't bother the
   lists with elementary questions without first browsing the archives.
