These two functions aren't that hard to implement run time into Gtk+.
If you look at gtkfixed.h (Gtk+ version 2.0 API) you can see that all
the children are stored in a GSList. You can iterate this list to find
the desired child, take it out of the list, re-insert it where you
want (all by using GSList functions) and emit an expose signal to the
GtkFixed parent widget.

SendToFront and SendTOBack are on windows also (primarily) used to
send an entire window to the fromt/back. On X this is the task of your
WM. (I won't call it easy)
