Yes, that's one good approach.

Another thing you can do is just have one column in your model, and
have that column contain a struct like:

 struct _RowInfo
 { 
   char *whatever;
   char *whateverelse;
   Foo *mydata;
   int foobar;
 };

Obviously the struct has whatever you want in there. Then register the
struct as a boxed type for memory management, and use
gtk_tree_view_insert_column_with_data_func() or
gtk_tree_view_column_set_cell_data_func().

There's an example of this in demos/gtk-demo/stock_browser.c, run
gtk-demo and you can see it in the source tab for the stock browser
demo.
