You can make interfaces that do not flicker but using just standard controls it's almost impossible because they do that in Windows itself if you make 100% custom created controls you can make it not flicker but that's a ton of work
You can however minimise flickering by being extremely careful about how you manage your refreshes - eg: refresh individual controls only, don't refresh the main window.
People don't tend to perceive flicker when a control is being updated with a new value as much as they perceive it when the control has been erased but redrawn with the same value (Andy's assertion by observation, haven't looked for academic research backing it up).
