Integrate ZeroTier's module into a webview type of app.

I need to create an app that simply shows certain URL, with ZeroTier's library libzt ([login to view URL]) integrated. This would connect to a network automatically, and use that to access the site. It's all there to be integrated, it's got clear instructions for Java, Python, Gradle, it goes above my head tho. So I'd like to receive a project folder for Mac, Windows, iOS and Android. Any lannguage. Just want to be able to add the network ID, and site URL, and build.
