How to generate a WD4A-Component?

Hi,

is it possible to generate a full WebdynproABAP component from scratch without using the workbench?

For generating ABAP-classic there exist several tools (ie.FunktionModules and methods) to save Dynpros, DDIC tables, function pools and classes in the system and to activate them; are there similar tools for WD4A?

Thanks in Advance

Sebastian
