I guess it depends a bit on how "Qt widgets to take advantage of a GPU"
is to be interpreted. I don't think that special GPU support for painting
some QPushButton was asked for. Playing a video inside a QWidget based
application might be closer.
When I look at my second monitor right now I see kaffeine (something
capable of playing videos with a Qt Widgets GUI) running, and if I am to
believe intel_gpu_top output it does utilize the GPU.
Some _something_ with Media, Widgets and GPU (keywords from the original
mail) works in practice.
