r.watershed --interface-description 2> gui.xml
open gui.xml in an text editor. parse the xml using some xml parsers i use pugixml and then create your own gui.
you can also make a standalone application if you link your application with libgrass* libraries
please see below your required xml output genreated by r.watershed

I am planning to change in GUI for watershed basin analysis.
Actually the GUI asking to many datas. I want to fixed the parameter to make easy to handle.

r.watershed is the module you are looking for…
folder is raster/r.watershed . Its not gui in python its C code you need to familiar with and in my opinion should swich to UNIX-like PC for these work and its my own opnion.
please dont start operating system wars!!!
gui is gnerated from an xml format .Each grass module have interface-description and based on that gui parsers will generate the form structure. What changes are you planning to make.?

IMHO for development it is better to have a Linux or Unix environment. so that you can compile from source modify code again recompile and follow the chain. In windows you have msys shell but you need to do a lot to setup an environment.
so switch to *NIX and come back. please dont start os or distro wars. dont ask the list to recommend an OS or linux distro. please…

Anyway i have to delivary the product in windows.
Try to understand my case.
Please tell me how can i compile source using msys.
I used this following command in grass65 -text.
“r.watershed --interface-description> gui.xml”
