How can I create a web site to show a map of languages in Europe?

I want to show on the map of Europe (with different colors)the languages spoken in Europe AND the changes that happened in the last, say 3000 years. I am thinking of a time selcting bar somewhere on the screen so one could select the period and see the distribution of languages. Or watch a show with the changes through history.
I am not much of a web developper. I was thinking to try flash, photoshop or even powerpoint. Any ideas how to build this effectively? Many thanks
