Correct me if I'm wrong but I have a theory or two on this. First off, THC IS fat soluble and NOT water soluble. What is that to say however, that it could not effectively be absorbed by corn syrup, an essential ingredient to lollipops.
Also, like someone ahead of me said, butterscotch lollipops may very well be a simple solution to this. Below are a few easy, online guides to home-made lollipops.

I still think that if corn syrup could in fact efficiently absorb the THC it would be the best bet, because while the butterscotch lollipops do include butter, its a pretty small amount, and would probably taste like shit after it became cannabutter. As I said, those two links above are just an example or two of the many, many availabe online tutorials to making lollipops.
Maybe someone who knows a little bit more about the properties of THC and the given ingredients in these recipes could find a way to make this possible.
Let me know if anyone has any ideas/comments,
