Question : Some sort of offline form that will save entries of data from several users

I've got  a client that wants to take a laptop to a convention and have a form setup where potential customers or whoever can fill out a simple form on it to save things like Name, Address. etc and have that entry saved in some sort of database. I know I can create a form in Word with those fields but They're not going to be able to remember to tell each person to hit save as so to not over wright the original and in that case I end up with 300 word files. I need something that will organize the data entered.  Has anyone heard of a solution like this.

I'm sure the website developer could put something on their site but this setup might not have internet access.

They can do this with a simple HTML form but they must have IIS or Apache loaded along with php or other scripting language on the laptop.  The laptop will act as a web host.
