what language would I use?

I'm trying to make a program/ app/ web page ( i'm not sure what would be the best way to do this) for myself and my fellow installers to use. The "thing" would have drop downs for who we are billing, what we installed, what kind of car. it would keep track of what we used that day and be able to email a list of what we had done to the office for billing. 1) can I do this as a web site and keep track of each installers different product and usage? 2) should it be a stand alone program able to be used by each person? If so what language would be best for something like this?
