Because treeview row objects don't receive mouse events and are not 
descended from Gtk::Widgets, try the following:

Use Gtk::TreeView::get_events and Gtk::TreeView::set_events to add the 
Gdk::2BUTTON_PRESS event to the others received by the treeview,  and 
then connect to the Gtk::TreeView::signal_event() function to specifiy 
your callback function.  Then, within that callback, determine which row 
was selected and then open your window accordingly.

If I'm all wet here, someone correct me, please.
