Communication with a store from the outside

[zzz9]

I'm setting up a small PrestaShop store and for reason of convenience for my commercial partner I want write a simple mobile application that monitors orders and shows alerts for the new of them. I am just a C++ programmer and not aware of professional web development. How can I communicate with my store's backend via http/https protocol? I know, there is already published android app on google play, but my commercial partner who will process the orders uses old nokia symbian phone that she likes too much. So I need write something namely for that platform. I need to mention that I have no external access to the shop's database for my hosting provider. Please, point me to some approaches I can use or PrestaShop modules that can help me there.

That's great, but this is android app. I need something for symbian, I need to know how it communicates with the store.

Thanks for the reply anyway.
