You dont need to create an exe file, pharo already comes with an exe file that contains the vm and pharo internals, everything else is in the image file. You can customize pharo to display only a specific gui, its a matter of creating the gui you want maximize it to whole screen and saving the image. Next time you open Pharo it will appear as it was when you saved it. You can also disable the world menu so your users dont have access to the pharo development tools.�
here are some valuable infos�
because Pharo is almost entirely coded in smalltalk you can customize it completely. How far you go to this will depend largely from your willingness to explore the system and learn about it.�
