GUI for UNIX

Help a newbie!
Just wodnering if there is an application (emulator, etc...) that will be able to read UNIX commands and bring back responses on the screen in Windows-like environment. I am looking for an app that will reside on a workstation (PC) and will querry the AIX server. If anyone can help, I would greatly appreciate this.
Thanks a lot!

putty is a good ssh/telnet client for windows. see this site: www.openssh.org
