Yes, you can, though you'll have to probably use the hated "eval()" function. But WHY do you want to do this somewhat unusual thing? I mean the user could just type their function into a script, and type their data into the script also, instead of your GUI, and run their script instead of your GUI. Is this just an arbitrary thing you want to do so that you can learn how to build GUIs?
