Hidding buttons is not supported by the GnomeDbDataWidgetInfo widget.
However, there are several things you can do:
1) copy the source of GnomeDbDataWidgetInfo (rename it to be one of
your widgets) and remove the unnecessary code, then pack together a
GnomeDbRawGrid/Form with your new widget
2) pack a GnomeDbRawGrid/Form with a button of your own for which the
callback function will call
gnome_db_data_widget_perform_action(rawform/grid,
GNOME_DB_ACTION_WRITE_MODIFIED_DATA)
3) use gnome_db_data_widget_set_write_mode(rawform/grid,
GNOME_DB_DATA_WIDGET_WRITE_ON_VALUE_ACTIVATED) for example, in which
case you don't need any button at all

In any case you'll have to create a GnomeDbRawForm/Grid widget first.

Hope this will help you,
