Cart66 + Gravity Forms + Buy One Click

Hello! I use Cart66 and Gravity Forms. May I realize such scheme:
The product of a certain category (for example, category Services) has a form with several fields, has first the button ('Add to Cart') on click on which the buyer remains on the current page (isn't sent to Cart), displays ajax message "Product #1 added to Cart" and the second button ('Buy One Click') on click on which the buyer sends to Checkout? Both buttons on click on one of them have to take information from the same form.
