If you want this, just go straight to FreeCAD and invest the time to learn it. It includes an OpenSCAD module but the interactive shape editing beats OpenSCAD for nearly everything (it's faster and more interactive).
I very much doubt a GUI interface is going to be faster than a text interface, in fact it will be the opposite. And then I'm wired to this one interface and have to poke around on lines with a mouse like its 1992. No thanks.
Also I can't easily compose or build composite objects, where is a one-line loop in Python. And how do I deal with libraries of components ? Dunno, seems like a step back to me.
I think you should do a little more reading, first. In particular, GUI design of 3D structures is almost always "Faster" than text-based, for multiple reasons. What I meant was that FreeCAD renders the reuslts of complex operations faster (for exmaple I often have to wait many minutes just to render a basic CSG tree in OpenSCAD). More importantly, FreeCAD is just a GUI for a Python object model that permits simple construction of complex objects (probably not a single line). See https://wiki.freecadweb.org/Manual:A_gentle_introduction#Man... for more about the Python API.
What's nice is that since it's a true Python API, you have total control over everything, including iterating over named edges of the object, which openscad can't do at all.
I spend many hours a day poking at lines with a mouse, and it's really more productive than typing a few things, rendering to make sure the result is what you want, etc etc.
