You can get field values in a button script just as you would in a field
definition. For instance:
http://library.gnome.org/users/glom/unstable/sec-calculated-fields.html.de#field-values

But unfortunately, you cannot currently use that same syntax to _set_
values. I filed a bug about that so we can implement it eventually:
http://bugzilla.gnome.org/show_bug.cgi?id=567041

In the meantime, you can set the values directly in the Postgres
database, using the pygda API. Unfortunately, like many Python APIs,
that's not really documented yet.

But here's a little example:
http://library.gnome.org/users/glom/unstable/sec-calculated-fields.html.en#using-the-full-pygda-api

There are other examples in my "Repository Analyzer" Glom system:
