GUIMINER?? - LITECOIN

[Chionce]

If I use GUIminer do i still need to mess aroudn with my cmd? i see many people telling me to put various commands into my cmd. Does GUIminer do it automatically seeing how its a GUI and scrypt? sorry if this is a dumb question. Also when will i actually see .00% of a LTC in my account i currently use GUIminer and coinotron Any information would be greatly appreciated
