I assume that you are talking only about inserting rather than appending.
Appending is easy:

Admittedly the insert() method should be documented:
http://bugzilla.gnome.org/show_bug.cgi?id=117964
but it's meant to work like similar insert() methods in STL containers. The
iter parameter isn't just some crap that you have to provide to satisfy the
compiler - it tells the method _where_ to insert your row. I think
ListStore::insert() and STL insert() methods insert before (or maybe it's
after - We should write those docs).
