Advice on Learning how to use Flex Data Services



Hi. I've been using flex for a while and I'm now at the stage
where I'd like to be able to develop AIR apps. I wanted to do
something simple to start have an AIR app on a few
friends desktops that lets users tick a box if they can make it to
a poker game. Do I need to learn another language like PHP to do
this or can it be done using just Flex? Other than the live docs
and dev guide that come with flex are there other
documentation/online info that can be recommended.
