First of all I'd suggest to have a look at libgda[1]. This library
abstracts database access and also provides widgets for database access.
Maybe those guys already invented the wheel you need.

Otherwise I'd implement a custom list store, which first just do a
"SELECT COUNT(*) ..." query to create empty rows, and then only fetches
rows from the database when some range with still empty rows get
visible. You'll easily detect the need for fetching more rows by waiting
for the tree view calling your list store's get_value() method.
