Web Site Building Software

I am in the process of planning a website for our office and am looking for a software package to create it with. We are running WindowsNT OS on the workstations and Novell 4.11 as our NOS. I want to let the individual unit supervisors to be able to update their portion of the site themselves. So I need a program that they can use (low to midlevel users) while giving me the power too build a nice site. HELP!!
