"native" is used for different things, from "use the platform's default gui toolkit" to "compile to a machine code binary". the former is a bit of a mess, but the latter is strictly better than wrapping a web view and shipping an entire chrome fork to display and interpret it. just write something in qt and forget about native look and feel, and the performance gain will be enough to greatly improve the user experience.
Should just use javafx or swing. Take a leaf out of intellij which while it as it's own performance problems (although not from the fact of the ui framework) has a fantastic ui across Mac / windows / nix
