14.1 GUI Basics 823 14.1 GUI Basics GUIs are potentially very complex entities because they involve a large number of interacting objects and classes. Each onscreen component and window is represented by an object, so a programmer starting out with GUIs must learn many new class, method, and package names. In addition, if the GUI is to perform sophisticated tasks,

Thus, regardless of GTK being written in C, it gives object-oriented help through GObject. Note that this item arranged help has nothing to do with C++. C++ has its own GTK library, called gtkmm.
