I had a similar problem, I wanted model-unrelated checkbuttons for each row
in my model, and I didn't like the treeview multi-row selection system. So
I did it this way:

- I created a two-column gtk.Table
- I put the TreeView in the first table, and the checkbuttons (but you can
use any widget, of course) in the second table
- I synced the checkbuttons size to the tv cell size by getting the cell
height via cell_get_size() method of TreeViewColumn, so that the
side-widgets are perfectly aligned to the tv cells.
- I used the row* signals of the model (mine was a ListStore, I don't know
if it works for TreeStore as well, it might be harder) to resize the table
and reorder-delete-insert the side-widgets as the model (and thus the view)
changes.
