How do make objectives with GTKRadiant

I cant find any tutorial that help you with siege objectives. say for example, i wanna make a point where offense have to reach to complete the first objective. how do I do it,
how do you change the spawn position once an object is complete and how do you print off message and give points to the player.
how do you make something carriable , like the code obj on hoth, and make a deliver spot. How to make consoles that people can hack say to green a door or something.
how to do siege classes.
lots of questions.
