I've been watching this for a while now.

Most interesting is:

https://github.com/snowfallorg/nix-software-center , a GUI software center for nix

And https://github.com/snowfallorg/nixos-conf-editor , a GUI config editor for nix

How big would the learning curve be for someone who’s never used a system like this? I’ve been slightly intimidated in using Nix. If this makes it easier to get in I’d love to try it out.

The web site has no info and only links, maybe throw something in the description next time because I have no idea what this is or how it differs from nixOS.
