The very idea sounds daft. It's not a perfect parallel, but this reminds me of systems like Qt Designer, or Apple's Interface Builder/Storyboard, or Android's XML layout system. Those systems all essentially give you an "initial render" made with one technology (XML files created in some sort of visual GUI-builder program) and "subsequent interactions" made with another (C++/Swift/Java code).
