You can overload operators in C++ (e.g.). Gtk+ is not
a programming language and has no operators to overload.

Sorry, I can't understand this.

if (GTK_IS_BUTTON(x))
return gtk_button;
if (GTK_IS_LABEL(x))
return gtk_label;
or
if (GTK_IS_BUTTON(x))
return GTK_WIDGET(some_button);
if (GTK_IS_LABEL(x))
return GTK_WIDGET(some_label);
or whatever. What do you need to overload?
