It's there already. The J script in Martin's package:
~/anaconda3/lib/python3.7/site-packages/jkernel/qjide.ijs
assigns IFQJIDE_z_ =: 1
As you might expect, jqt doesn't set IFQJIDE_z_ =: 0 by default, so you
need to test the flag e.g. like this:
if. {.@".'IFQJIDE' do. …
not like this:
if. IFQJIDE do. …
The said script qjide.ijs repays perusal. It defines a locale: 'qjide'
which implements a "web window driver" (wwd).
This includes a verb: qtqjide --a simple Qt webview browser.
It also invites you to specify a path: WwdStart --to a startup script.
I haven't investigated it too deeply, but I can't get the WwdStart script
to run when Jupyter first runs "jkernel",
which it does the first time a notebook tries to execute some J code.
Maybe it's only intended for the builtin IDE-replacement "wwd"?

Nobody challenged me on this bit of nonsense. It's chicken-and-egg…
• Either the notebook must use Python instead of J
• Or, write it as a J lab.
I'm going to do the latter, and once it works, offer it on jwiki.
But once jkernel has been installed, there may be a use for it in migrating
jkernel to a new J release.
…But of course, this is the central thing Anaconda is meant to handle for
you. Not just be a cross-platform pacman cum launchpad.
