Constructor, creating and showing a button.
+The preferred way to create standard buttons is to use default value of
+\arg{label}. If no label is supplied and \arg{id} is one of standard IDs from
+\helpref{this list}{stockitems}, standard label will be used. In addition to
+that, the button will be decorated with stock icons under GTK+ 2.

Note that under Motif, calling this function immediately after
