I know HNers will hate me for this but how about Electron with Vuejs? You don't need access to network, have full access to file system, sqlite, etc and engineers for Javascript/HTML are dime a dozen so may not need to learn a new language. Also in case you need to switch to another OS it's cross platform by virtue and can be easily ported to web easily should the need arise one day.
