Google Groups and Zend Framework

Zend Framework allows you to interact with Google Lists ..  see below

I have to check this out, is this the same as Google Groups ?

Interacting with email lists

Email lists allow several users to retrieve email addressed to a single email address. Users do not need to
be a member of this domain in order to subscribe to an email list provided their complete email address
(including domain) is used.
Each email list on a domain is represented as an instance of Zend_Gdata_Gapps_EmailListEntry.

Creating an email list

Email lists can be created by calling the createEmailList() convenience method:
$gdata->createEmailList('friends');
Email lists can also be created by instantiating EmailListEntry, providing a name for the list, then calling
insertEmailList() on a service object to upload the entry to the server.
$list = $gdata->newEmailListEntry();
$list->emailList = $gdata->newEmailList('friends');
$list = $gdata->insertEmailList($list);
