knowledge in ABAPWEBDYNPRO

Hi experts,

i know ABAP, I want to learn ABAPWEBDYNPRO(here onwards AWD).

from one of threads here, i went to tcode SE80 and checked there, i cant see the AWD in the dropdown.I am confused.

Firstly i want to know what all are required to learn ABAP.

I heard NWDS is required, why? What all things has to be done before using tcode SE80? what has to be configured? How the process starts?

I have searched many threads here and even help.sap.com, but it is quite confusing for me.

So kindly help me on this, points are rewarded.

regards,

NtK.
