I'll leave any discussion on the differences between WebKit and KHTML
to other who know more about it than me.
But no, WebKit is in no way tied to Qt, and there are active ports of
WebKit from Mac to Qt, GDK (or GTK, or something), and the WX toolkit.
Much of the design of the architecture of WebKit has changed over the
last few years, and as part of this KWQ no longer exists.
At a very high level WebKit now has 3 components
or less completely cross platform
* WebCore -- The rendering and layout engine
* WebKit -- Provides the system api
JSC is basically crossplatform so i'm ignoring it
Only WebCore and WebKit require substantial platform work. The WebKit
component/module/thingy is the interface between JSC, WebCore, and the
host platform, so by it's very nature is more or less entirely
platform specific. As time goes by we're trying to reduce the size of
WebKit down into a much thinner layer to make porting WebKit (the
WebCore is the really interesting bit, the majority of it is cross
platform, however different platforms have different networking
libraries, rendering libraries, etc. So we have a number of
abstractions that wrap platform specific API, eg. PlatformMouseEvent
(to wrpa mouse evevnts), DragData (that maps platform drag and drop
information), and so on to varying levels. The rest of WebCore is
then written in terms of those abstractions, so that is necessary to
port webcore to another platofrm is to implement versions of those
abstractions for the target paltform. (though that's a big "all")
You can see most of this at work in the WebCore/platform directory -- http://trac.webkit.org/projects/webkit/browser/trunk/WebCore/platform
I've probably made a few mistakes, but i don't doubt that other people
will swoop in to correct any wild fallacies on my part...
