You need to get your hands on a Kickstart ROM image.
Once you have the ROM image in place, you can create a directory on your XP harddisk and point the Amiga hdd to that directory (WinUAE->Hard drives->Add Directory). Install Workbench and whatever else you may need there.
If you don't own an Amiga, you will have to obtain the kickstart and Workbench files illegally. Posting guidelines forbids me to tell you how, but I'm sure you can figure it out somehow.
You should now be able to boot WinUAE to a useable state.
As for the programming part, I HIGHLY recommend using
AmiDevCpp which runs on Windows. Keep your ADC project on the Amiga hdd, compile it, and run the .exe in WinUAE. AmiDevCpp is free, faster and easier than doing it under WinUAE.
That's how I do it, and it works for me...
Hope this helps.
