Write a custom data handler implementing the GtkTreeModel  
interface.  Googling "custom list model" should turn up some  
guidance.  The iface->get_value method is where you'd fetch the  
required data.  All you need to do to the tree-view is put it in  
fixed-height mode, so that get_value is called only for visible  
rows.
Good luck!
