There is an ebuild for it already, although it is in an overlay on github. Probably needs cleaned up but as I don't want to install QT on the laptop I'm using, I haven't looked too much at the ebuild, just noticed a few minor issues with it (no noting that it's a prebuilt binary and to not warn for the QA issues as a result) and not using the unpacker eclass off the top of my head.
