Sort Affiliate Links by Incoming Hits

Apologies if this question has already been posted. I searched but was unable to find a similar topic.

Is there a plugin (or similar super-easy way) available to display links in my sidebar, but order them according to how many incoming hits they’ve generated to my site? I don’t want general referrers displayed, but links that I specify (blogroll or affiliates).

I’d appreciate any help that you can offer ??
