Both Facebook and Netflix implemented their eponymous apps with Web. Despite spending millions of dollars, neither of them could achieve an iPhone-like user experience (60 frames per second and less than 100ms response to user inputs) on anything less powerful than a system-on-chip (SoC) with four ARM Cortex-A9 cores.
In contrast, numerous products like infotainment systems, in-flight entertainment systems, harvester terminals and home appliances prove that you can achieve an iPhone-like user experience (UX) on single-core Cortex-A8 SoCs. Our above-mentioned manufacturer HAM Inc. (renamed for the sake of confidentiality) verified these results by building both a Web and Qt prototype.
In this white paper, Burkhard Stubert explains how he could save one of the world's largest home appliance manufacturers millions of Euros by choosing Qt over HTML. The secret? Qt scales down to lower-end hardware a lot better, without sacrificing user experience.
With a five times smaller footprint, four to eight times lower RAM requirements and a more efficient rendering flow than HTML, Qt provides faster start-up times and maintains the cherished 60fps and 100ms response time, where HTML would struggle. The calculations show that being able to just downgrade your SoC by just one tier like this, Qt can reduce your hardware costs by over 53%.

That headline's like asking if you'd prefer to be kicked in the left testicle or the right.

Speaking as a pretty in-depth QT developer - hundreds of thousands of lines of c++ / QT class based code - I enthusiastically second your opinion.
Also, once they move on and leave your version of QT unsupported, you get to be kicked in both. For no good reason at all except "drool, new, shiny" on the part of the QT devs themselves. Idiots.
QT's cross-platform capability is great - until you run into bugs, and/or until they leave you behind. Then things get... interesting.

The left. It's the sinister one. After time to think it over though, I'd almost always rather get kicked in the crotch than do any sort of GUI coding beyond what I do on the site here; the pain doesn't last nearly as long. Give me a nice, simple shared library, a CLI utility, or even something running on some microcontroller's bare metal any day of the week.

I wouldn't. I'm smart enough to not try running idiotic GUI bullshit on a microcontroller.

Even if the configuration GUI runs on a device-that-is-not-a-microcontroller and sends the finished configuration to the microcontroller, you still need a framework for the configuration GUI that runs on a device-that-is-not-a-microcontroller, whether said device-that-is-not-a-microcontroller runs Windows 7, Windows 10 in S mode, GNU/Linux, Android, macOS, or iOS. Which GUI framework for an app that runs on a device-that-is-not-a-microcontroller is preferred?

In that specific instance? HTML. Either internet or local network accessible depending on your specific needs but it makes zero sense to allow multiple devices to have configuration change permissions when it can be done more easily and securely from a centralized source. Ideally the devices to be configured wouldn't even accept incoming traffic at all but would instead poll a server at regular intervals; admittedly this is not always viable.
