APEX

I'm wondering if apex is a good choice for an application I need to build. The application will need to have a map showing geometries. From a quick read of the internet this seems pretty reasonable to do in apex, by connecting to something like google maps.

However we will also need to be able to select an object on the map, or select all the objects in a box selected on the map - is it going to be reasonably simple to get these geometries back from the google map so that in apex I can see what has been selected?

I've used apex a bit but as you can tell am very new to the idea of maps and searching through a map. If any one has an example app so much the better!

Cheers
