It's possible, but I'm skeptical, because the hard part of coding isn't "typing words into a text editor/IDE." It's thinking algorithmically in enough detail, with edge cases, fallbacks, error handling, etc, that most people struggle with.
Squarespace is actually a good example; someone still has to write all the nifty widgets and figure out how they'll work together for a pleasing experience. If putting an attractive visual layer on top of code was all it took, then Smalltalk would have won decades ago and everyone would program.
The main barrier to "no code" and "everyone can program" is still the mode of thought, not the mode of representation.
This has parallels in artificial intelligence, where as soon as a problem is solvable by a computer, solving the problem no longer counts as "AI" (chess, natural language processing, even sentiment analysis!). Similarly, as soon as a problem is made easy and accessible to non-algorithmic thinks, programmer move on to the next thing that requires that mode of thought. Maybe we'll exhaust the problem space of potential programs someday, but I don't see any evidence for it.
