For non-programmers, the GUI is the only interface available. The GUI is also much easier to use than the programmatic interfaces, since it is easier to point-and-click on buttons than it is to write and debug code. |

One of the major disadvantages of using any GUI is that if it does not have the functionality to do what you want it to do, then you are simply stuck. Therefore you must have to look what is happening deep inside or behind what you have seen in a nice GUI. |
