How do I make a pushbutton execute a function that used to be done after user input was given?

I have a successful code that I am trying to modify to be completely displayed in a GUI. I have a few functions that used to be executed after a user typed either 'y' or 'n' for yes or no in the command window. I'd like the function to now be executed upon the push of a button. Does anyone know the easiest way to do this?

function pushbutton_callback(src,event)
   [outputs] = your_function(inputs)
end
