Database driven website for normal food, milk, bread(needs to be easy manageable)

Do you have any ideas for a grocery store as a webdesigner? what language you should use? We need to handle customer orders and see what kind of products elderly centers and small hospitals has ordered. So we can view those products, pack them in the car and drive to the locations. Payment system is not needed in the project. just a page to view their orders and edit and delete the orders. Add new products fast and convienient, delete and mange the orders convinient and fast.
