The fork can certainly be changed. Some recently-made frames have a mount for a rear caliper as well as for V-brakes or whatever they shipped with. If you have one of those you're in luck. If it's a steel frame, the right kind of steel, and fairly sturdy, a caliper mount could be TIG-welded on. Then you will probably also need new hubs, although some wheels you can buy have hubs with disk mounts and also rims with brake tracks to make them "universal", so you might have those already.
