I need some advice on what language and what type of database to use to create a program for my company. We would like to develop a web-based application where users can access a database over the internet and over our LAN. We would like the front-end to have the feel of a Windows application (forms, text boxes, command buttons, etc.) The database could potentially have 100,000 records in it and the users would be adding, editing, deleting, searching records. There would be 1-5 users connected to the database.

Any advice would be greatly appreciated. Thanks in advance.
