grab the label from the button (cast its child to a Gtk::Label and
call get_text(). store the string and a pointer/ref to the button in a
vector. sort the vector using a less_than orderable functor based on
the string. then iterate over the vector calling reorder_child.

never tried it, might have some complications, but i think it should
work. pretty basic STL programming, though STL programming is itself
not common enough these days.
