I am evaluating if Qt is suitable for a commercial C++ project I am planning.

I need to develop under Vista (don't even ask), but the final product would also be deployed on osx and linux.

I am a one-man company, so costs are important, but I would like to know what development tools people are using under WINDOWS. My two main options are

Eclipse CDT with Qt integration
SlickEdit

I do not plan to use Visual Studio (cost), unless there is a real benefit.

Does anybody have any pointers?

Thanks,

Keith
