You need to add the path to where your files are located since they
are not in any of the "standard" path directories where Python looks.
To do this, you can add the following lines in your files:

import sys
sys.path.append(/path/to/obj)
sys.path.append(/path/to/gui)

import obj
import gui

#etc..

Hope this helps
