There was some interesting discussion on https://www.reddit.com/r/plaintextaccounting/comments/16xhjm... about GUI's for plain text accounting; anyone tried Paisa? Looks nice for those who don't want to learn gnuplot
Fava is also very good (for Beancount; hledger can export to it).
hledger-web is much simpler than these and can be good for less technical users.
