Craft Commerce - On the fly product / product from entry form

Good Evening.

Does anyone know if the following is possible within Craft Commerce

1. Can data from normal entries be used to populate a one-off on-the-fly product?
2. Can an entry form be used to create new products or can they only be entered only in the admin section?

Any thoughts on the above or suggestions of other ways to create products from the front end would be appreciated.
