Please note that (Python) scripting is possible via the GUI as well. There is a
Python tab and a simple Python script editor integrated (since at least
version 7.4). Simple examples are also included. I don't use them, so I don't
have an opinion about their usability.

There is also the wxGUI Graphical Modeler. It too has the script
editor integrated. In 2008, I requested for such an option:
https://trac.osgeo.org/grass/ticket/131. Not speaking Python at the time,
I asked for help to learn. I think it can be a good starting point in Python
scripting for GRASS GIS. The 'Help' menu offers links to various
resources. Adding one or two more resources, like
https://github.com/wenzeslaus/python-grass-addon, is meaningful.
