Can't connect to localhost:8080 when trying to run Google App Engine program
I have to manually start python and make it point to my app folder, for instance in a command line window on Windows I am using python.  I installed python in C:\Python27 and my sample app is in c:\GoogleApps\guestbook
C:\Python27>dev_appserver.py c:\GoogleApps\guestbook
and then I can start my app in the Google App Engine Launcher and hit localhost 8080
I'm trying to run the Google App Engine Python 2.7 Hello World program and view it in a browser via Google App Engine Launcher. I followed the install and program instructions to the letter. I copied and pasted the code in the instructions to the helloworld.py file and app.yam1 and verified that they are correct and in the directory listed as the application directory. I hit run on the launcher and it runs with no errors, although I get no sign that is has completed (orange clock symbol next to app name). I get the following from the logs:

Running dev_appserver with the following flags: --skip_sdk_update_check=yes --port=8080 --admin_port=8000 Python command: /opt/local/bin/python2.7

When I try to open in the browser via the GAE Launcher, the 'browse' icon is grayed out and the browser won't open. I tried opening localhost:8080 in Firefox and Chrome as the tutorial suggests, but I get unable to connect errors from both.
How can I view Hello World in a browser? Is there some configuration I need to make on my machine?
