Install a specific package with debtap

Hello gents!
Discovered a nifty little program that I want to install, called Wireguird.
Searched for it in AUR or otherwise, there is no package version for Arch baswed dstros.
The Wireguird has a .deb package, and one can install it with debtap…
However, found out that debtap can disrupt your packge manager flow, so I stopped before I could inflict more damage to my system.
Any ideas how to get this package installed or converted?

The general answer is “make a PKGBUILD”.

Either by building it from source or by extracting the contents of the deb in the PKGBUILD which there are many examples of.

In this case, it looks like it would be very easy to build from source in a PKGBUILD.
