[dba-VB] Browser based database

I need to do two different browser based databases (I think).  I know nothing about this.  Both 
clients need to enter data and have multiple users hitting the database from home and office computers.

Where do I start?  I am getting pretty good with C# / SQL Server but those are computer based 
"applications".  If I could do an internet download installation, I could probably (maybe) go there. 
  Except what about admin rights etc.

Is asp.net viable?  Is it close to C#?  If I keep the data entry screens simple can I do it in C# 
and then just "press a button" to turn it into ASP.net? Please don't make rude noises here.

;)

I just know nothing about internet facing application programming and I feel really inadequate on 
this stuff.
