I've just added a new library KJSEmbed to kdenonbeta that makes it easy to 
embed a KJS interpreter in a KDE app. The lib includes bindings that let 
scripts access QWidgetFactory (so they can load dialogs/widgets from 
QtDesigner .ui files), and a binding to the properties of QObjects.

If you want to know more, look at the kdoc comments or try building the 
example app by running 'make testkjsembed'.  Here is section that illustrates 
things a little:

    // Setup Interpreter
    KJS::Object global( new KJS::ObjectImp() );
    KJS::Interpreter *js = new KJS::Interpreter( global );

    // Create Console Widget
    KJSEmbed::JSConsoleWidget *win = new KJSEmbed::JSConsoleWidget( js );

    // Add Bindings
    win->addBindings( js->globalExec(), global );
    KJSEmbed::DialogFactory::addBindings( js->globalExec(), global );

    KJSEmbed::JSObjectProxy *appProxy = new KJSEmbed::JSObjectProxy( js, &app 
);
    KJS::Object appObj( appProxy );
    appProxy->addBindings( js->globalExec(), appObj );
    global.put( js->globalExec(), "app", appProxy );

    KJSEmbed::JSObjectProxy *consoleProxy = new KJSEmbed::JSObjectProxy( js, 
win );
    KJS::Object consoleObj( consoleProxy );
    consoleProxy->addBindings( js->globalExec(), consoleObj );
    global.put( js->globalExec(), "console", consoleProxy );


I hope to add support for the scripting interface Ian Geiser is working on 
soon. Where should this code live? Personally I'd prefer kdelibs, but 
kdebindings might also be suitable.

Note: There IS a security mechanism, and NO this WON'T make the kjs in 
konqueror insecure - only the specified interpreter has access to this stuff 
and only a defined set of objects and properties is made available to scripts.

The current code can be viewed here:
