Free Pascal has excellent support for OpenGL, Gtk2 and Qt 4
Gtk2 headers come with Free Pascal preinstalled, and they are the same as using Gtk2 on c for example.
You can find Qt 4 bindings here:
OpenGL also works very well with Free Pascal.
What specific problems did you find?
and far too often I've been stymied by bugs in the compiler.
In this case, please submit bug reports. Free Pascal teams is very quick at fixing bugs. Acctually I´ve working on very big projects with Free Pascal and I haven´t ever come across a bug on the stable releases.
The only times I found bugs was on very experimental ports, like the Windows CE port.
