How to convert the django web application into the desktop application
There are two places you can go to try to decouple the view and put it into a new desktop app. First you can use the existing controller and model and adapt a new view to that. Second, you can use only the existing model and build a new view and controller. 
If you haven't adhered closely enough to the MVC principles that you can detach the model from the rest of the application, you can simply rewrite the entire thing. if you are forced to go this route, bail on django and http entirely (as duffymo suggests above).
You have to also evaluate these solutions based upon performance requirements and "heaviness" of the services. If you have stringent performance requirements then relying on the HTTP layer just gets in the way, and providing a simple API into your model is the way to go. 
There are clearly a lot of possibly solutions but this is the approach I would take to deciding what the appropriate one is...
