Creating a custom multi-step registration

Hey,

I know that this has been asked a few times already, but i'll take a chance and ask it anyway.

I have installed Membership, but i want to customize the registration process into a multi-step process of my choice. I know that it currently cannot be done from Membership at this time, but how could i customize it then? Could be done just by short codes and scripting from inside a page, or is there a plugin or widget that does the trick without having to delve into coding myself?
