I know QWidgets are no longer "interesting". Even KDE moved on from
them...
Take a look at:

https://github.com/anormann1974/vsgQtViewer
I haven't tried any of it, but you are probably going to want to do
something like the QtViewer thing does. Claims to put a VukanSceneGraph
inside a Qt widget. If you also have access to the Vulkan library you
should have access to the methods allowing direct GPU access. With a bit
of reading and a touch of luck you should be able to use Qt Widgets and
stuff all your graphing logic into some of the multiple GPU cores most
recent video cards provide.
None of my video cards are high end. I think the weakest one I have in a
drawer has 16 CUDA. Most of my machines have 384 CUDA because they are
GeForce GT 630 based.
I did find one statement interesting in the Features list:
Multithreading support at the viewer level, file loading and database
paging.
If they really pulled that off it would theoretically mean every one of
your frequency graphs could be its own thread in its own GPU doing its
own thing.
Your application would have the wholesome built-in look of Widgets and
your graphics would be doing their own thing in their own space.
