/**
    A very simple application that show your name in a message box.

    This demo shows how to use NWG without the NativeUi trait boilerplate.
    Note that this way of doing things is alot less extensible and cannot make use of native windows derive.

    See `basic` for the NativeUi version and `basic_d` for the derive version
