You can try out the Telerik Platform and Getting Started Tutorial to see if it will work for you. It will guide you through the process of building a simple image gallery app that allows you to take pictures with the camera and store them in the cloud, so that if someone else installs your app, he will see them. Just go to http://www.telerik.com/
, click on "Telerik Platform" in the top right corner and Sign Up. If the Getting Started Tutorial does not start automatically for you, you can start it from the "Getting Started" button in the top right corner and click Quick Start Lessons.
I hope you enjoy the tutorial and building your first app.
