That is indeed supposed to prove the look-and-feel integration of Qt apps in/with the other desktop applications (YMMV) but a priori it's independent from the issue at hand. In practice you might even lose certain (subtler) style features because of differences in the theming capabilities (very limited in GTk3). As a compromise it will probably work better to find a native Qt widget style that matches your GTk/Gnome theme (check out the highly configurable QtCurve), or use one of the few styles that provide native implementations for Qt and GTk (Breeze and apparantly Adwaita).
