WSL is a linux VM running under Windows. As such it has the same limitations with regards 
to GnuCash and the Gtk Inspector. That is Gtk Inspector running under WSL can't 'inspect' 
GnuCash running natively on Windows.

But that's not important as the inspector is part of Gtk3 and available anywhere Gtk3 is used, 
including Windows. The trick is to know how to enable it. The general idea is that if 
environment variable "GTK_DEBUG" is set to "interactive" while gnucash is starting, the 
inspector will be started. How to set environment variables is platform dependent, but the 
mechanism works on all platforms (I have just tested Windows and linux).

For convenience I have just now added a snippet to our Gtk3 wiki [1] to illustrate how to set 
the variable using the "environment.local" file in path/to/etc/gnucash. Again this path/to/etc/
gnucash varies per platform, but its contents will be the same everywhere. And it's only one 
way to do it. Any way that sets the environment variable prior to gnucash startup will do the 
trick.
