Qt Design Studio on MCUs

Write a concept (descriptive) topic that covers the following:  

What is Qt Design Studio and what can you use it for when developing a MCU-based device. It should also include a brief explanation of where it fits in a typical dev workflow (design tools, embedded IDEs, Qt Creator), and where to find more information (links to MCU Quick Start Guide for example). This part can be structured so that there is one paragraph depending on whether you are:

1. a technical artist
2. a GUI/app developer
3. a HW developer

Describe the basic workflow from a role-based perspective, but remember to focus on the tasks rather than the roles.
