Recent version of cairo supports Qt by allowing to draw to a surface created with cairo_qt_surface_create(QPainter *painter): you can inspect the relevant header file here. There's no documentation because this feature is still experimental and disabled by default (you should compile cairo yourself explicitely enabling the Qt support with configure --enable-qt.
