You can see the code I use for Barry's Emacs on github. Barry's Emacs
uses PyQt for its

Here is the script that builds the app:

https://github.com/barry-scott/BarrysEmacs/blob/master/Editor/PyQtBEmacs/
bemacs-windows.cmd

It uses https://pypi.org/project/win-app-packager/ to do the heavy lifting.
I have already built the python extension that is used by this point in the 
build process.

Then look at this script that builds the setup.exe:

https://github.com/barry-scott/BarrysEmacs/blob/master/Kits/Windows/build-windows.cmd

It uses Inno installer from http://www.jrsoftware.org/isinfo.php
