You want vectors, that's what you want. If you trace the outline of each country, you can draw and fill each one in a single X call (I don't know if this translates to a single GDK call); you can fill them any colour you like, scale them as much as you like, and it'll be fast and won't use much memory. Actually getting the vector data could be a little awkward but I'm sure it's on the net somewhere.

You won't get textures inside each country but from your description I don't think that's what you're intending anyway.
