Adventure/Achievement maps?

I want to make an adventure map that would award achievements for visiting areas and/or collecting items. Is this something easy to accomplish with the existing release?

I apologize for being noobish here; I have a world that I intend to keep adding to until there's no more room in it. I know many people are downloading it based on certain particular features I've included, but I think that if I could make it into a 'treasure hunt' challenge, more of those folks would spend more time checking out the rest of the place.

Would it be possible to create a map with X amount of achievements built in, that would display a mc achievement alert, along with the current percentage of achievements?

I'd probably include secret locations on the map that would reveal the achievements list - but not necessarily their locations - along with lots of clues everywhere about how/where to find other clues/accomplishments.

Any input is appreciated. Thanks!

I have no help for your idea other than putting this post in the appropriate section.
