As luck would have it, I recently pulled together a list of no code tools into a market landscape: https://www.createwithoutcode.com/posts/no-code-development-...

I'll be adding more in the coming days...

To directly answer your question, I would recommend Bubble.is as a great place to start in the no code space.

In terms of lowering the barrier to coding, Bubble.is is doing some interesting things: https://bubble.is/

They did just that in the coursera course "Software Engineering for Software as a Service". A VM is available for download and as a rank amateur I found it a great way to dive in. https://www.coursera.org/saas/
