Is it possible to port Gravity form entries to Mailman?

Tired of wrestling with Contact Form 7 am seriously considering going Gravity!

I really don't need all of the bells and whistles of Aweber and my Host provides an auto-responder for small lists, based on Mailman.

The normal embed code from Mailman looks like

Code

<form method="post"
 action="http://lyoursite.com/mailman/subscribe/yourlist">
Subscribe to our list:
<input type="text" name="email">
<input type="submit" value="Subscribe">
</form>

So would I be able to at least have the name email fields ported if I decide to go a head with gravity!

And if it is possible would it be possible to accomplish without extensive coding experience?

Thanks

Chris,

Could I get a copy of this and how to use the code?

I am already a customer.

Thanks.
