Why don't you try to get started on GTK radiant and see if you like map-making in general? Pretty easy to use and also fun. I've been a map developer at a few servers using only GTK, I've made some pretty dope maps but unfortunately I've lost all progress on my old HDD.
I've been planning to make new maps for FG, unfortunately life keeps getting harder and I have less and less time by the day. PM me if you need help starting on GTK
