How Qt can be used to port a text editor to a simple C/C++ based environment ?

[pprrateekk]

I am new to software porting, knowing next to nothing, so a detailed response will be appreciated..

I have a simple C/C++ environment with simple OS like features like memory management, multithreading but no in-build support for UI. How Qt can be used to port a text editor to such environment ?
The original text editor is available for both linux and windows platform, so which will be easy to port ?
On both platforms it has GUI, but new environment does not support it yet, so where should the changes be made ? Lets say new platform gets capability of GUI, then where should we start, and what should be done.
