Qt DLL's needed to publish emulator?

[Claudio L.]

I know other projects have Qt-based emulators.
I'd like to know how the WP34S emulator (or other project) in Qt was packaged, what DLL libraries are needed? I'm planning to release the Qt-based newRPL emulator for Windows and I'm not sure what DLL's need to be packaged.
Other operating systems are not a problem, as the user can install the Qt packages and is good to go.
Is there a good (open source) installer creator?

Thanks in advance.
