Is there any good working qt wallet for windows?
Yeah, the wallet is working well. Look in the first post in this thread for download link. This is a very old coin, but it syncs quite fast.
If you need more clearnet nodes you can add these from novaexchange:

most peers on clearnet are very outdated wallets which are long incompatible.
