Does anyone have Wireguard setup using Luci?
Yes, I do.
Do you have an inquiry, or are you experiencing an issue with Wireguard setup via LuCI?
Yes... it's quite common and easy to do as long as you've installed luci-proto-wireguard.
Although the guides reference the command line, it should be pretty easy to adapt to using LuCI.
I know that @egc has some excellent guides, although I don't know if they provide LuCI or CLI instructions (or both; I've never read them, but I know they're well regarded).
Are you encountering a specific issue that requires assistance? Your question is otherwise too vague for us to help.
The link never comes up. Been trying to Fill-in-the-blanks no luck. found excilent inst for wifi but nothing for WG
There could be many reasons for what you are experiencing, but it is not related specifically to LuCI. Using LuCI will generate the configuration just the same as using the CLI, but obviously the values need to be correct and there are other things (outside of the config itself) that can also affect things such as your internet service and your remote device.
That said... Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:

WireGuard Server Setup Guide
WireGuard Client Setup Guide
The guides use LuCi to setup.
Using LuCi gives some insight to the users where to set things and what it means, using uci commands is a kind of a blackbox but of course very fast if it works 
Besides using LuCi the guides also cover the config files
