Even in platforms that _have_ "NetBeans UI Builder" like tools people tend to not use them. I and my iOS developer friends don't actually uses storyboards for actual UI in non-demo apps because it gets quirky and it's a lot easier to define from code. In Android (and other UI systems like WPF) declarative markup (XML) is often used directly with the view only used to see changes without having to compile (a problem web doesn't have, and Android is getting better at).
