ASP.net on ISS web page design

Hi,

 

I want to create a web page displaying the status of several systems. Each one will be represented by a square box.

 

The boxes will fill up in either red or green (<50% will be red and >50% will be green).

 

Can this be constructed in HTML? Can anyone guide me to the best language to use for this if not? Also, I have to use ASP.net to do this.

 

Thank You

Hari
