this isn't true. the problem with this "intuitive thinking" is that it
starts out thinking that a button is a widget with text in it.

that's not what a button is. a button is a widget that when clicked
upon (or some equivalent keyboard action is carried out), emits
certain signals. what is displayed inside the button ... this has
nothing to do with the button itself. it could be a label, it could be
a pixmap image, it could be a table that contains other widgets of
various types, etc. etc.

abstraction is good, specialization is a necessary evil. you want a
specialized button that *only* has a text label. GTK gives you the
abstract button that can contain anything you might want.
