I need to add a shopping cart icon with a number of items in cart on all my pages.

So I feel that the most effective way to have a site wide shopping cart link would be to have an icon in my menu bar at the top of the page (basically in the wordpress menu bar). I know that there is a site wide shopping cart widget but I am wondering how I can create an menu bar shopping cart icon that shows how many items are in the cart.

Please let me know. I have done .php in wordpress and understand it well enough to usually figure out how to code with wordpress.

Thanks
