I've tried BlueGriffon a couple of times, and each time I gave up on it after pretty quickly. One problem was the need for various plugins, the most useful had to be purchased. I wasn't sure enough of the quality and hesitated to make the investment. Besides, documentation was pretty sparse about its UI features, which made it not so easy to use. Interestingly, I was looking around the net recently for a simple web UI builder. Pickings were quite sparse, either online tools attached to some cloud provider, or elaborate proprietary systems way more than I needed. The ironic thing is that current "front-end tools" still require tediously writing out the UI whether in JSX, JsonML or whatever, pointing up where GUI tools would be most useful. It's crossed my mind that writing a web UI generator in, say Tcl/Tk, would be possible and quite surprised no one has done it. ATM I don't have the time to pursue such a project, but a small GUI application to produce the "boilerplate" part of the code would be particularly helpful.
