Can i use the new ipod nano WITHOUT ITUNES?

The iPod is designed to work with iTunes. There are alternative iPod managers for Windows but they do have a few major drawbacks.
The iPod software updater is integrated into iTunes so .....
1) You can't update the firmware on your iPod if a new version comes along
2) if there are any problems with the iPod you can't restore it's firmware to fix them.
3) If purchasing iTunes Music is something you wanted to do you won't be able to buy from the iTunes Music store.

If you really want alternatives, they are out there.

However, it would be better to see if you could fix the issue you're having. Details about your computer (which OS especially) would help.

No. You need to use some program to do the syncing. Without a program, the iPod will not recognize the music.
