  The point of this exercise is to accomodate both a screen-reader and a
sighted user in a sane way, so if a status bar has no special status
then it is not very useful.  Besides, I can't find any prior art for
status bars in dialogs, nor would glade seem to let me do it at all: you
can't seem to put a status bar below the OK/Cancel buttons (and you
can't put it above since it has a resize handle).  I do not think it
would look right anyway.

  I could just use a label and it would look fine and give the behaviour
I want.  The problem is controlling when it will be read by a screen
reader.  It seems like using a text area would make the user experience
really intuitive for a visually impaired user.

  That said, I could implement my own widget that supports the use I
want, my question is whether this is something worth supporting in Gtk+
itself, or is my use case invalid for some other reason.
