GUI Popup Window Layout

I've been trying to get an answer to if doing something like this in Unity 3D is possible or not. As you can see from my rough little sketch I want my pop up windows to have a photo of each product, a close button to close the pop up window, some descriptive text about each product and finally a "Buy It" button that will open up a web browser and take them directly to the product online so they can make a purchase.

I'm using the Free version of Unity 3D and my target out put is for the Stand alone player. I'll need to make lots of these pop up for not just the over 200 items in my gift shop but also a similar pop up window for all the artwork in my Interactive Art Gallery.
