Try installing the cordova cli
npm install -g cordova
Then run
cordova create new_directory_name com.example.hello Hello\ World
This will create a new directory "new_directory_name" and generate a app with id "com.example.hello" and title "Hello World" (you may need to escape the space between Hello and world some other way. The \ works on *nix but I see you are on windows.)
Next cd into the new dir and run
cd new_directory_name
cordova platforms add android
After this all phonegap commands should simply work.
