See RenderThemeGtk.cpp and ScrollbarThemeGtk.cpp. You will quickly see
why repurposing that code is not going to be practical... these are not
GTK+ widgets in any real sense of those words, they are drawn manually
and at great effort using the terrible GTK+ foreign drawing API. These
are just normal DOM widgets styled to look like GTK+ widgets. You're
looking at a major engineering project touching the internals of
WebCore if you want to allow real GTK+ widgets into the DOM.
You will have more luck using WebKitGTK+ 2.4 API ("WebKit1") where this
was supported and everything was in one process, but keep in mind this
old insecure version of WebKit is being removed from Linux distros and
is not suitable if your application is ever going to process untrusted
