Are these libraries friendly each other and self-sustained?
These are the only libraries you need to work with Telegam API and to support Telegram calls respectively. You may need other libraries or frameworks to implment UI and media files processing.
I can proof that it is possible, we built a Telegram app for Ubuntu Touch with it, and it works pretty well.

Do you have it opensource?
I​ need​ it.
You can look here: https://gitlab.com/Flohack74/teleports -Basically there is an internal lib called qtdlib which does bindings for QML. And it uses Quickflux for message passing in QML.
