As you might have noted in Wammu 0.14 announcement, I made Wammu for Windows reality. At the end there is more support for that than I expected :-). All you need it to download full installer and everything will be done automatically including start menu entry.
Wammu on Windows looks almost identically as GTK version on Linux, there is really no big difference as you can see from screenshot.
It revived my memories about creating native Windows application years ago as I used same tool for creating instalator (Inno Setup). It works still same way and is very easy to use even when I didn't remember anything from time I created installator for CodeConv.
