Hey man, I think the best way to go here is sending an email to: cos311@osprey.unisa.ac.za . I'm using Netbeans IDE that makes use of the C++ with QT plugin.
I'm not sure if the plugin works on the Express edition but I use the Qt Add-in for Visual Studio 2008. Try and see if it will work for you.
When you are ready to submit your assignment, right-click on the project in the Solution Explorer and select "Create basic .pro file", just take that generated project file and your source/header files and all should be fine for the assignment.
Mention in your assignment answers that this is what you've done since the project file will contain comments stating it was automatically generated.
