That doesn't really look like file:// URL.  It should be spelled 
"file:///c:/index.html".

Inherit some COM object from IWebUIDelegate, implement the interface and 
put MessageBox call in the mentioned method.  Next call 
IWebView::setUIDelegate() passing the above UI delegate object.  When a 
javascript alert occurs, webkit will see if it has the UI delegate set 
and if so, will call it's runJavaScriptAlertPanelWithMessage() method.
