You could perhaps also try Reddit at /r/personalfinance or /r/pftools.
I'm actually quite interested in this since I've tried to use GNU Cash for budgeting, but it isn't exactly designed for budgeting (it can work). I actually started building a web UI for it, but I lost interest.
I hope you get good feedback, and I'll try to give it a good, solid try tomorrow. No need for the gift card.
