C# forms app web interface, Problem

Question

Hi

I have a windows forms application and I need it to have an web interface.
So I need the user to see his inventory in the web and add things to it.

Is it possible to do this with C#? I don't know ASP yet.
I searched the web but didn't find any good tutorials.

So how would you do this?
Please refer me to good tutorials if you know any.

Thank you
