While Qt5 has always been promoted as being friendly towards Wayland and working to avoid its Linux dependency on X11, with the upcoming Qt 5.4 release is going to be the first version where there's out-of-the-box support for running Qt applications under a Wayland compositor -- i.e. integrating the Qt Wayland module.

The QtWayland support for Qt 5.4 is considered a technical preview with support of QWidget-based apps being less than ideal, the QtCompositor API in QtWayland not seeing a release for Qt 5.4, and other work still needs to be pursued. The QtCompositor API for the QtWayland module is what's needed for those out there wishing to write their own Wayland compositors using Qt. Qt's support for XDG-Shell is also less than complete and there's also not any official sub-surface protocol support for QtWayland.

Find out more about the Wayland support in Qt 5.4 via Robin Burchell's blog. Qt 5.4 is currently in alpha with a planned official release around mid-November. Besides the QtWayland module, there's many other new Qt 5.4 features. This is also the first release done by "The Qt Company" as Digia's spin-off.
