For KDE development I would recommend the KDE Neon developer edition as it has all the tools you need to get started.
Blink the web engine Chromium is using is a fork of the WebCore component of WebKit,which was originally a fork of the KHTML and KJS libraries from KDE. So it is other way around. You are right I the sense that the biggest contributor to WebKit is Google.
