How to make an addon like Firebug?

Question

I am basically a dotnet developer(beginner). I need to make an IE addon just like Firebug in Firefox. I need HTML and CSS features of Firebug, don't need the other features. I would like to know where should I start with and which platform should I choose. I would prefer dotnet, but if not possible can go for others as well. I have made a FF Toolbar that connects client's database, but have no idea about the Firebug kind of addon. I need to make it only for IE. Can someone help me with links, code snippets and/or some theories that would guide me to make my project. Thanks for any help :)

Regards

Developing something like Firebug is a huge undertaking for someone who I'm assuming has not written a Firefox extension before.

That said, there's an introduction to developing extensions for Firefox on the Mozilla blog, and something similar for IE on MSDN.

Finally, is there a reason you need to write something yourself? Firebug works pretty well, and IE has Developer Tools
