I would recommend going with Qt over Electron any day. You'll have an app that's fast, responsive, easily be multi-platform, have the look and feel of a native app on every platform (Windows, macOS, Linux), is light-weight, doesn't hog a lot of memory. You'd also not be trying to twist and bend over backwards to try to use something that was designed to display documents (HTML and DOM) to construct apps (with all the overhead that comes with it), and instead be building atop a framework that was created with desktop applications first and foremost.
