Autocomplete attributes form and quantity. Add directly to cart from filter.

[aldileka]

I am working on a shop that sell tickets (virtual products). The tickets have attributes like zone(that every ticket will have a unique zone where will be the event), date, type of ticket(that will affect on the price). I want a filter on home page with those attributes and also a field to put the quantity. After this the button buy which will put directly the product on the cart, without a results page.  Exactly like on this site geoticket.it
I have searched for modules but never faced something that can do this.
Have you faced something like this? Or can someone can help with a general idea how I can implement this functionality?
Thanks in advance
