Hmm, I also didn't get it so I feel tempted to ask :-)
say for example, I have a c program called square, which takes an int as input and returns the square. And I want to make a GUI for this program with feelin. One text input, one button, and a text area for output. User enters a number into the text input, and presses the button. Feelin reads the input, calls square with the parameter given to it, and writes the answer to the text area. It would be great if there was a tutorial which explains the event handling for this task, also explaining how to interface with the c code (or executable) from feelin.
