These kind of applications you want to build require access to xorg api, dbus and many others.

Your best options here are gtk or qt.

If you don't want to use c/vala for gtk or c++ for qt, you can use python which have bindings for both libraries, just search for pyqt or pygtk.

And both qt and gtk offers unofficial bindings for several languages.

Beyond these, your best shot could be flutter, because Canonical is building lots of libraries to make flutter an alternative for Linux desktop application development.
