In this example [1] I managed to use a WebView without a
window. Although you you might want to either use an xserver that runs on a
framebuffer [2] and to put the webview in a window or to use
a GtkOffscreenWindow [3] instead of a window.

I had mixed results when using an offscreen window with a webview. I got
the best results when I use a standard gtk window and run the program in a
framebuffer xserver.

You can connect to a webview's signal 'resource-request-starting' and
decide if you want to allow the extra resources to be downloaded or not. To
reject a resource set the request's uri to "about:blank"

Take a look at this sample program [4]

I hope that it helps.
