The only tool I've used that used native language was Buildbot, from which I still have the scars. Not because of the native language, but from the versioned documentation that didn't match behaviour of the given version, and the complex workflow that had zero examples because "everyone's setup is different" - so you had to figure out their words for terms, and build your config from scratch. It was an entirely unpleasant experience.
