Bitx40 varactor tuning/tuning dial?

I have been looking at buying a Bitx40, and I see from the specs that it has varactor tuning. I have never used varactor tuning before. I have heard that you can use a multi-turn potentiometer for tuning, but I was wondering ho you would go about making (or purchasing) a dial or other display to work with the varactor tuning so you know exactly what frequency you are on?
