Well, I've been lurking for many months and this is my first post ever !
However Amiga Forever is based upon WinUAE, but it also gives kickstart files for various versions of AmigaOS... don't remember whether it contains the WB disks or not, but maybe yes...
However the answer to your question is 'yes' because WinUAE can run AmigaOS in a window on your desktop as well as full screen.
Other emulators are not so featured and supported as WinUAE is, so I think it is the only real choice you have.
