how to write setup.py for this application structure?

Question

I have written an application with python (2.7). The structure looks like:

kent$  tree myApp
myApp
|-- foo.py
|-- gui
|   |-- g1.py
|   |-- g2.py
|   |-- g3.py
|   `-- __init__.py
|-- icons
|   |-- a.png
|   `-- e.png
|-- logic
|   |-- __init__.py
|   |-- l1
|   |   |-- __init__.py
|   |   |-- la.py
|   |   `-- lc.py
|   |-- l2
|   |   |-- __init__.py
|   |   |-- ld.py
|   |   `-- lf.py
|   |-- logic1.py
|   |-- logic2.py
|   `-- logic3.py
|-- myApp.py
`-- resources
    |-- x.data
    `-- z.data

Now I am about to write a setup.py to distribute my application. I am new to this. After reading the py doc and doing some testing. a few questions come up:

1. how can I (or should I) package my root package (myApp) under /lib/python/site-package ?

   since in my py file, I reference resources/icons by relative path. for example, in foo.py there could be icons/a.png and in gui/g1.py there could be ../icons/e.png and so on

2. how can I package icons and resources directory?

   It seems that package_data and data_files won't copy the two directories to right place.

3. is this the right way?

    packages = [''], package_dir = {'': ''}, package_data= {'': ['icons/*.*', 'resources/*.*']}, 

   after install, my files will be:

    /usr/lib/python2.7/site-packages/icons/*.png /usr/lib/python2.7/site-packages/resources/*.data /usr/lib/python2.7/site-packages/gui/... /usr/lib/python2.7/site-packages/logic/... 

4. Is there problem of my application structure?

   should those resources/icons/whatever files go to certain python package, not under the project root? so that in setup.py I can use package_data to copy them to right place.
