Visual Basic + Access for LAN

I hope to design a database for our company. It needs to be running in a LAN. Now I?m still not very familiar with SQL server, but know Access much better.
Is it possible to design this database by Visual Basic + Access 2000 (for LAN)?
The key point is data sharing and users management. From my previous learning, normally we need to split Access database for LAN use, but then need to share the database completely. It?s not safe.
Can someone give me some directions, and where to find teaching materials?
Do I necessarily need to learn programming with Visual Basic + SQL?
