Qt: How to create a Windows DLL (which exports functions)?

I need to create a Windows DLL that exports functions and has a graphical user interface. The reason for the GUI in a DLL is that the DLL serves as a kind of plugin for another third-party application. Currently, I only have access to Visual Studio Express, which AFAIK does not support MFC, so I'm looking for alternative ways to create a GUI in a DLL. After some research, I came across Qt, which seems promising. And it seems that it would be easier to use the Qt Creator IDE rather than Visual Studio Express.

However, how do I create a Windows DLL in Qt Creator? (I think a regular DLL, I don't think COM or a managed DLL will work)

UPDATE: I got this job! After jumping through several hoops, two important keys should have added

#include <windows.h>

And then use the Math Migration Framework tool (currently officially available at: http://qt.gitorious.org/qt-solutions/qt-solutions/trees/master/qtwinmigrate EDIT: I believe this is a new link: https : //github.com/qtproject/qt-solutions/tree/master/qtwinmigrate )

I used this example to make me move:

Add the following line to the .pro file: TEMPLATE = lib

This is almost all you need to do to make QtCreator turn your application into a DLL.
