Hello. Wanting to start learning mapping. But was just wondering if programming education needed, or any experience in programming ?  Thanks in advanced.

To make a map you need no programming experience. You make the map in Radiant, and can use script-placer tools that generate the needed scripts for your map.
When you start adding custom features in your map, you're going to have to edit scripts at some point. Normally there's tutorials around that could help you out, or some of the forum members offcourse.
