Can't bind port in Google App Engine Launcher - wordpress

Question

When I try to deploy my app locally I can't get it running. This is what it's telling me:
2014-10-24 13:16:08 Running command: "['C:\\Python27\\python.exe', 'C:\\Program Files (x86)\\Google\\google_appengine\\dev_appserver.py', '--skip_sdk_update_check=yes', '--port=3306', '--admin_port=8000', 'D:\\Documents\\Clever-CV Project\\wp39 - Copy']"

And I am a noob - so there's a very good chance I did something stupid, but I'm at my wits end and have found everything I could online to try.
My SQL instance is running, the database passwords work and connect locally and to the remote app CloudSQL instance.
My app.yaml file has a new version name
the wordpress config file has the root names/passwords set-up correctly

The issue with running your app locally is in this part: '--port=3306' which is mysql's default port and you said mysql is already running which means that port is already taken and cannot be used by your app. Instead of 3306 try the default 8080 port and increase it by one (i.e. 8081, 8082, etc) in case you need to run multiple applications at once.
