I'll take your hot opinion and replace it with mine: Gnome (3) is hands down the worst DE in the entire Linux ecosystem and is actively harming all others by merely existing due to the mentality driving its development: "fuck everyone that's not us, we set the standards and you will like them".
Currently KDE is the most polished and feature complete of the "batteries included" DEs. And even then as a developer I prefer a bare-bones tiling set-up, picking and choosing what I want and having an experience customized to my preferred workflow.
So which other DE on GNU/Linux does provide the same tooling and platform abstractions as KDevelop/Qt Creator do?
GNOME has a very nice HIG from UX point of view, but it is stuck in C + POSIX as technology stack in what concerns developer experience. Vala is still not there and I don't believe in JavaScript for native UIs.

Same or similar? It doesn't matter what they provide because I'd go with ScalaFX(http://www.scalafx.org/) + IntelliJ or Vala|Genie + Vala IDE. Mono is also an option if you're into it.

KDE? Seriously? It's one of the worst DEs on linux. Any DE which isn't based on gnome is just cheap nowadays.
