It can be with help. Check the link below and read very carefully. Also, there is some detailed info in John Bridges book and the manufacturer may have some info. It's not all that hard but there are some things that can go wrong and if it does go wrong you can end up with a huge mess. I would suggest doing a small test area first to get the hang of it. Also search the main forum from link below and search on self leveling. I did a large pour and I asked a ton of stupid questions on that site before starting (as I always do :) ).
Be aware that the stuff is expensive.

One other thing that I realized before I did my pour and you never hear anyone warn about this -
Obviously what you are really trying to do is flatten your floor not necessarily level it (they are not the same). However, since we are using gravity we will get both with SLC's. A problem can arise when one end (or an area in the middle) is much lower than than some other point. The difference between your lowest portion and highest will define your min thickness of course. If this is more than 1" or if you run out of SLC before reaching the thickness you could be in trouble. Better to know before hand. It's not all that easy to check this measurement but it can be done with a level and some shims (or maybe a laser?).
Alsways buy moe SLC than you think you need. You can return the excess.
