I need to develop an embedded linux application with menus and corresponding screens (similar to phone menu and their corresponding screens). Before that I need to develop a pc based simulation for approval of customer. The same is to be ported on to the embedded platform after it is finalized.

I've installed Qt Creator 2.3.0, Based on Qt 4.7.4 (32 bit) on Ubuntu. Is this the right IDE for developing Qt embedded applications. Now I'm trying to figure out which project (Qt quick / Qt Widget / .. ?) to choose for simulation purpose. Can the simulation software be ported on to the embedded linux platform ?
Where & how do I get started?
Thank you.
