You can simply use PCL's PCLVisualizer, which is extensively described here, via the QVTKWidget. This is the setup I'm currently running. So you would end up doing something along the lines of the following (pseudo-)code:

In your header:

class PointCloudWidget : public QVTKWidget
{
    //Whatever comes before (constructor, methods, etc.)

private:

    pcl::visualization::PCLVisualizer m_visualizer;
};

And in your cpp:

PointCloudWidget::PointCloudWidget(QWidget *parent) : QVTKWidget(parent)
{
    this->SetRenderWindow(m_visualizer.getRenderWindow());
}

You can then use the visualizer to achieve the same functionality as the PCL viewer has.
