well, since the column headers are just buttons AFAIk, you can do the
same for the row headers. So, I would write a GtkCellRendererWidget,
which can be easily based on the GtkCellRendererToggle class already
available in GTK 2.0. That is, you need to create a
Gtk.CellRenderer-based class which is able to render widgets on cells.

no, it's part of gtk-extras, a 3rd party library.

then, the CellRendererWidget approach seems the best way, so you can add
any widget you want to the cell.
