A function that attempts to return all values as strings seems  
limiting.  For anything non-trivial I would suggest using  
webkit_web_frame_get_global_context to retrieve the frame's  
JSContextRef then using the JavaScriptCore API directly.  The GTK port  
may like to provide convenience APIs for conversion between the  
platforms string representation and the JavaScriptCore string, similar  
to the CoreFoundation variants in JSStringRefCF.h.  If convenience  
methods like those were added then it would only be a handful of lines  
of code to do what you request using the existing API.

Kind regards,
