How to import a module from a directory on level above the current script

For my Python application, I have the following directories structure:

\myapp
\myapp\utils\
\myapp\utils\GChartWrapper\
\myapp\model\
\myapp\view\
\myapp\controller\

One of my class in \myapp\view\ must import a class called GChartWrapper. However, I am getting an import error...

myview.py
from myapp.utils.GChartWrapper import *

Here is the error:

<type 'exceptions.ImportError'>: No module named GChartWrapper.GChart
      args = ('No module named GChartWrapper.GChart',)
      message = 'No module named GChartWrapper.GChart' 

What am I doing wrong? I really have a hard time to import modules/classes in Python...
