Hi,
Added a Qt export example to white_dune 1.222 as
wdune-1.222/docs/export_example_c++/qt_opengl_example/
So you can click/drag your 3D application part in white_dune
and click/drag your 2D application part in qtcreator/qtdesigner.
A screenshot of the example is here:

white_dune has no sponsoring for fedora, but you can always use the
fedora 30
port on
https://wdune.ourproject.org/
so long
