When is the launch? I have been waiting for some time and no news?? I was told that only the GUI wallet was needed for launch?

Official launch date will be announced tonight.
The GUI and website launch of today is still beta stage, the official IOTA launch won't happen over a random forum post, there'll be tweaking left to be done to GUI, website and the only thing that matters: core client. But the current incarnation of the simple GUI is as userfriendly as physically possible, enabling everyone to donate to Foundation, test the network for themselves, complete pending trades etc.
