I kinda wish someone would take SQLite and make something like Access on top of it.

Many years ago, there was a project that tried to do just that using Tcl/Tk, which seems like a fine choice - Tcl is very simple and easy to understand even for on-programmers while its deficiencies aren't really important in this niche, and Tk is one of the easiest UI frameworks around to use. Unfortunately it petered out and I can't even remember the name anymore...
