Why don't you use the LCL?

I just ran your code and it worked fine. Probably you have some kind of error in your gtk2 installation.

I just download gtk2-runtime-2.16.6-2010-05-12-ash.exe from here:

http://gtk-win.sourceforge.net/home/index.php/en/Downloads

And your code worked. With Lazarus 0.9.28.2
