What bit do you need help on?
Is it building a UI?
Is it clicking a button?
Is it sending the signal?

For example can you send a signal outside the GUI,
say from the Python >>> prompt?

Does your GUI display OK? Wjhat toolkit are you
using to build it?

Can you print a message on screen when you
press the button?

Show us whatever code you have so far and we
might be able to help.
