I was using that particular example of a list control as an example of
what one would look like.  Many applications use list controls to many
different effects.  My only public (at the moment) GUI application (PyPE)
uses list controls to hold results lists for a find-in-files result, as
well as a list of 'todos' (delimited by #todo:what, or its equivalent in
other languages).  Almost every filesystem viewer in the history of
computing has also used the rows and columns approach, as does pgAdmin
to display the results of SQL queries.

Technically speaking, any toolkit which allows for scrolling and the
laying out of controls in a grid would be sufficient to implement this
(optional column-title buttons for sorting would be convenient, as well
as draggable column widths; as has been demonstrated almost everywhere).
