Creating a new group based on gf field

I have a GF developer license with the following add-ons loaded: User Registration , Stripe, Post Creation, and of course, ItThinx Groups.

With this combination, is it possible if a new user enrols in a premium membership and creates and names their own “Group” (a custom post type), that the itThinx plugin can create a new group and apply it to their registration?
I am aware of

if ( !Groups_Group::read_by_name( $shed ) ) {
$group_id = Groups_Group::create( array( ‘name’ => $shed ) );
}

but I don’t know how to use this in conjunction with the GF plugin.

Thanks,
Torben
