Add custom table in Magento backend (LI)

Our customer have a Magento, [login to view URL], where all products are marked with a multiselect attribute with att code "shipping". It tells which shipping service(s) the given product should be sent with. What we want is a custom made button on the order pages in backend where the shop owner kan click, and it will show how the products in the order should be shipped, based on those attributes. Attached you see there button should be, and a word file showing an example of the table popping up in a _blank window. The solution should be prepared for making more options than the current two to the attribute "shipping".
