It can be done BUT the key thing IMO, as was mentioned, is if you are mechancially inclined. If you can rebuild say a small engine or the like successfully(sp?) then you could prolly handle it if you take your time. If, on the other hand, you dont even like the thought of putting in a light bulb then it would prolly be better to let someone else do the rebuild/removal/instal.
Some special tools are required but they can be purchased or made if you have a decently equiped garage and youre not in a hurry to get the trans rebuilt.
Im NO expert on 700s and have only recently rebuilt my second one. I got a bunch of info off this board and by scouring this site
www.transonline.com If you go to that site look in the upper left corner for "total tech database" and click on it. Then pick the make of trans you want info on (GM). Then go to 700R4. Lotsa info, tips, and descriptions in there.
A board member (Hu Ryde) has lots of info on the trans on a site also.

If you dont wanna make the special tools you'll need thes ppl have them for sale. I havent purchased anything from them myself but it looks like they offer just about any tool you would need to tear down/rebuild a 700R4.
