How to make desktop gui in kotlin?
Am I right that you mean desktop GUI, not web?
We don’t have a lot of specific Kotlin libraries for GUI. You can stick with usual JVM frameworks for GUI like Swing, etc. There some utilities for Swing in standard library, but that part is very likely to be reworked in near future. Also there is third-party KotlinFX library, which is JavaFX adapted to Kotlin.
You can use whatever GUI toolkit available for Java. You can also check out KotlinFx (https://github.com/eugenkiss/kotlinfx).
