Replacing programme dial on Indesit W1060?

I have just pulled the programme dial clean off my Indesit W1060 washing machine, meaning that the only way I can select the appropriate programme is to do so with a pair of pliers.

Is it possible to simply replace the programme dial by itself or do I need to replace the entire front panel? Either way, do I need to be a qualified repair engineer to be able to do the job, or can anyone do it? Also, where do I get the parts?
