It won't be a problem if you use AVCWare iPod
to iPod/Computer/iTunes Transfer, even though you don't have iTunes library.
It helps you to add audio and video files from your PC to your iPod/iPhone, such as music and movies. On the other hand, it can also transfer files from iPod to computer.
Wish this can help and good luck.
I think its step by step guide is most helpful.
It is easy to use and you can try it now.
