I'm about to head out, but I wanted to give you a tip to get you started.

I recommend checking out the wp-admin/index.php file. This should serve 
as a template for your custom app.

You'll also need to look at the $_REQUEST['redirect_to'] query arg so 
that you can properly redirect your user once they've logged in. You can 
find more about it by looking in the wp-login.php file.
