All I want to do for now is just adding the terminal in gnome-pie applications. The thing is, I don't even know what should I type in "command to execute" path.
One remark: It is much easier to configure Gnome-Pie by drag and drop: Simply search for the Terminal in your main menu and drag it to the Pie's preview!
Second remark: Nearly all of your application links (desktop files) are stored in /usr/share/applications! You can navigate with your file browser to this directory (File System -> usr -> share -> applications) and drag your desired applications to the configuration menu!
The command you're looking for is
gnome-terminal
