So if that's how you feel, you use JWt ( http://www.webtoolkit.eu/jwt/ ) instead of Wt. Same thing, different language. JWt is a native port of Wt to Java, not a set of jni bindings.
Wt (http://www.webtoolkit.eu/) makes developing C++ web applications dead easy. It is similar to Qt: you work with object oriented widgets and events are delivered through a signal/slot mechanism. You get Ajax, javascript, cross-browser portability and all the nifty stuff for free.
