You can do this extraction/merging easily with intltool, and let translators work with PO files.

You might find a better reference to this in the Gnome or Intltool documentation, but here's a 1-minute overview:

1) In your ./my.desktop.in file, prepend localizable entries with '_'
E.g.
_Comment=A Comment
_Name=Name of Application

2) Create a ./po directory and create a POTFILES.in file where you add 'my.desktop.in' to the list of source-files

3) Now you can run in your ./po directory 
intltool-update -p

You will now have a POT file in you ./po directory for translators to translate

4) After translation, you can merge changes back into your my.desktop file doing something like:
intltool-merge -d po my.desktop.in my.desktop

Feel free to catch me on IRC if you need any clarification.
