I'm not sure exactly with a GtkTree, but the following works for a
GtkCTree. I would have thought similar is possible. If not, just use a
CTree with one column and no titles...

      GtkCTreeNode *a_node; 

      while (GTK_CTREE_ROW (a_node)->parent != NULL) {
	 /* Do anything you want to the parent node */
         parent = GTK_CTREE_ROW(a_node)->parent;
      }

This will stop when it finds a node with no parent (ie. at the root of
the tree).
