Setting up and Debugging a WCEM Application

Hi Seniors,

I am new to web channel and have a few questions regarding it.

1. What all things we require to develop a web channel application?
2. What technologies it involves?
3. How to Debug these applications?
4. What are the configurations, setup file and plugin's required to get started with WCEM development?

Thanks in Advance.
