Depending on what exactly you need to do, it could be easy enough, or 

For the simpler case, where you just want to add an interface to one of your 
classes, you just need to create a QObject and mark your methods as slots.

See the QWebFrame documentation page.
Check the addToJavaScriptWindowObject and javaScriptWindowObjectCleared

If you need to return JavaScript objects or arrays from your method, it's 
something I'm looking into at the moment -- is it possible at all? Is there a 
way to obtain the page interpreter, or the current execution context?
