I have a project to port from Windows to run on Fedora.Right now I am looking at the possibility of porting the same. Application has the following main components.

1) This is a tray application which interacts with the Windows Services
2) The project has many COM components written in ATL
3) It uses the Win GDI for drawing images on the monitor
4) There are DLLs exposing the interfaces for certain functionality

There is GUI part in this application also( For easing the development, I thought of making use of the Qt).I am wondering if someone can share the experience what is the best way to do it as I am new to the Linux development.

Thanks in advance.
