I believe Pépé has an advanced degree in actuarial science but I pretty sure he remains opposed to teaching people in general about J :)
I'm not sure how J's GUI compares to, say, Shiny for R but a colleague who has done a little programming put together a pretty nice dashboard using Shiny in not too long a time. I have used the J GUI once or twice and recently pulled up an old piece of code written in it and it mostly worked; I had to make a tweak to hide the JQt session and there are two other behaviors I'd like to correct but it's good enough to ship. So, seems pretty simple to me but I've only done a simple thing with it. However, J has no parallel when it comes to typing in small, powerful verbs and using them with real data, if that's any attraction. I used J the other day because a colleague had just spent 10 minutes trying, and failing, to do something in Excel I did in a minute in J.
