Hey there,

If I've understood you correctly, that's basically what you can do with the 
'Objects' browser in GammaRay:

The object browser tab allows you to edit static/dynamic properties of a 
QObject-based class and trigger slots from within them.

The property editor in GammaRay is also able to manipulate object properties 
that were registered within the Qt meta object system by using Q_PROPERTY() 
[1]. This in combination with being able to call slots on the object is 
basically what you want.

Have a look at 'core/propertyeditor' if you'd like to see the code that deals 
with this logic. That's what we use in the 'Objects' browser tool.
