Converting Windows DLL to Linux SO

[alunw]

I have written some software which has a GUI interface on Windows using a DLL, but only a text interface on Linux using a .so file. What I am wondering is if I can use Wine to port the Windows DLL to Linux and have then use the resulting .so instead of my original .so to finish up with a GUI Linux application. My whole UI is inside the DLL/.so and the rest of the application is more or less identical between Linux and Windows.
If I can do this it will save me a lot of time having to learn X windows programming. I don't think I can use any kind of IDE as I am creating all the resources my own resources from data stored on a relational database.
I'll probably just set off and see where I get to, but I'd be grateful to hear from anyone else who has experience of porting DLLs to Linux using Wine.
