Simple point and click programming tools are not a stable state.
The problem is people start using them. Then they have collective needs. Then the tool adds complexity to make those needs go away. Thus begins the slow process towards the tool no longer being simple and/or maintainable.
You could do it, but you’d need a Craigslist-like “we’re not adding anything, it seems to work ok” attitude.
That attitude is totally incompatible with VCs, who generally set the tone in this industry.
There have been a bunch of attempts, but nothing takes off really. I think the closest is LiveCode which used to be proprietary but was open sourced some time ago.
It's been decades and I've still never found a better way to make simple GUI applications.
