use a filter on the sort model:

  GtkTreeModel implementation (list store, tree store, etc.)
  +---- GtkTreeModelSort
        +---- GtkTreeModelFilter

you just need to remember to convert the iterators given to you by the
GtkTreeView widget *twice*: one from the filter to the sort model, and
one from the sort model to the real model.
