Custom Add to Cart Elements

How can I edit the add to cart form so that the submit button "add to cart" is wrapped inside a div element

Also, I Would like to be able to change the text on the button without having to use of String Overrides module https://drupal.org/project/stringoverrides

Another thing I need to change the label "quantity" to something else and could not find any way to customize that label either.
