You can do non-default things with cell renderers as described here:
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ch08s02.html#id2510771

The CellRendererText cell renderer has a "markup" property that you can
use instead of the regular text property. Or you could use the
"foreground" property:
http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1CellRendererText.html

The set_cell_data_func() callback might be a good way to use this, but
other people have more experience with that than me:
http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1TreeViewColumn.html#a19

That should just be a matter of changing the correct data in your model.
The view should update automatically.

There are various popup/combo custom cellrenderers out there. There is
even one in examples/customcellrenderer. Also, there is an example in
examples/book/treeview/ which shows a popup context menu, if that's what
you want.
