On Windows, Electron-based apps generally bundle Electron (Chromium and Node.js) with the app, resulting in a large download size. You can do that with Windows Qt apps as well, and it generally works out too (the app is larger than a Win32 app but smaller than an Electron app). I have less experience with GTK but I assume it works the same. Linux distributions expect Qt and GTK apps to use a system toolkit. Some like Arch try to package Electron apps the same way (using a system Electron). However Electron releases incompatible major versions often, and you often have to install multiple Electron versions in parallel for different apps, and which version changes over time, so I have to juggle installing/uninstalling "electron" and "electron12/13/..." based on when apps update. (Admittedly, I also have Qt5/6 installed and GTK3/4 installed, but I expect these version numbers to remain stable for the next 5+ years.)
