Ask HN: Rich client platform recommendation

I'm out of touch with modern desktop tech and want some suggestions for a data navigator app I want to build.

Long ago I had looked into Eclipse RCP, Netbeans, Adobe AIR, and JavaFX. Today we might use Electron or maybe something Qt-like. I'm looking for cross-platform (web optional) with some UI elements or window management and some light graphics like icons that open to tables or such. I fast edit/test cycle is very important. Prefer static language envs but ok with js-like if framework/tooling adds a lot.
