I'm making a RTS game and want to make a toolbar on the bottom like all games of that type. (with a minimap on the right and buttons an the left) First of all, does that thing have a name? cause I have the gimp and I googeled gimp toolbar tutorial and only got descriptions of gimps toolbar. Also, is there a good way to make it, or a place to get one (for free)? Any help or advice would be helpfull cause I'm totally clueless. Thanks.

Its called a HUD (heads-up-display) or UI (user interface). You'll rarely find a specific technical UI tutorial. For design, there may be articles, but the best way is by examing other RTS games for what works and what doesn't. For the technical/artistiic side, you're just going to have to learn the software.

This book really helped me out when I was designing my user interface.

I would highly recommend it.
