The GTK/TreeView works a bit differently to WinForms. In concept, it's
a bit like the TreeView is databound to a TreeModel-implementing
object such as TreeStore or ListStore.

For your purposes all you need to do is to have a columns in the
TreeModel that is not displayed in the TreeView.

Also, there's a more .NET-ish subclass called NodeView/NodeStore that
lets each row be an arbitrary object.
