Dear PradaP,
I admire your spirit and your commitment. If you don't try, you'll never find out.
Excellent approach getting a JAA-license and learning the language - we already have too many immigrants of the wrong kind who aren't making any effort in this direction or to familiarize with the country itself and its inhabitants.
The DLR test is is quite a hurdle to overcome - even for the native speaker - but the biggest show stopper will be the right to live and work in the EU. Contact the German Embassy or look up for more information under:
Auswärtiges Amt - Startseite, there switch over to English (if you wish) and click on the button labelled 'Welcome to Germany'.
Maybe your girlfriend can find a job including a sponsor before you do. Then you just marry her and that should take care of your residence and working permit... Good luck!
