Add Quantity to Category Condensed Product List

For my product system, product detail pages are unnecessary for the customer end. Product lists within the subcategories are the primary sales interface. WIth that in mind, I have set the cart system to display the 'Condensed List' by default (and only option), as in this image from the demo products:


Just prior to, or within the ADD TO CART column, I would like a QTY: ____ user input box, which naturally, is passed on through the cart.

I am new to smarty, so any tips/explanation would be greatly appreciated. Thanks!
