gtk_frame_set_label() is a bare wrapper function for the set_property call; it's a pure convenience method. The reason we use properties is because it's OO; subclassed widgets can override the property accessors. Also, it's useful for bindings; e.g. in pygtk <object>.props gives the collection of the object's properties. Without the formalism of GObject properties that wouldn't be possible.
