However it will be difficult for non programmers. The very first dialog about Google Maps has menus "API provider" and "Query". I wonder how many non programmers know what they are. They can take a guess and learn but maybe this is still too low level. The second example is about building a login form by configuring its input fields. Maybe adding a completely configured dialog would be good enough for non programmers. Programmers can edit the details. Same for every other component.
However I remember that non programmers didn't use Visual Basic, as easy as it was. Programmers did. Some non programmers built sites on MySpace some 10 years after VB, then wrote on various blog platforms and configured themes, then ended up on Facebook and other non programmable social media platforms. Outside the Web the most used non-programmers programming tool is still probably Excel. I've seen amazing stuff build there from people who couldn't write a two lines script in Python.
