In that case I suggest you start by at least skeeming through the tutorial present in Qt's documentation.

ahoy,
check the the following thread:
http://www.qtcentre.org/forum/f-qt-programming-2/t-qglwidget-qeventdispatcherglibprocessevents-performance-problem-12714.html/?highlight=OpenGL

it contains the working source code of a multi-threaded image viewing and manipulation program that uses QGLWidget with scrollbars. hope this spares you many hours of coding.
cheers
