is there a full-featured framework for C that is similar to Qt?
It’s called GTK+ (Gimp ToolKit). It’s actually quite nice to use, and any program that you write using it will also work on KDE! It’s syntax is also pretty nice (for C). It’s syntax is very close to Qt’s (see for yourself in this tutorial).
