How to clean launch a GUI app via the Terminal (so it doesn't wait for termination)?

Tho whole problem is that if I run a program from Gnome Terminal(e.g. gedit something) the program Gedit runs, but if I close Gnome Terminal, the program Gedit closes too.

I know Alt+F2 exist, but I want to use Gnome Terminal.

Any help is really appreciated. :)
