Is there any way to contact the makers of bitcoin qt and bitcoin core? Would like to talk to the makers of bitcoin qt and bitcoin core. I have googled but cant find an email address or a way of contact!
It's open source software by many independently cooperating developers. The name is now Bitcoin Core, where bitcoin-qt is the GUI application.

Discussions happen on many forums and media, so it depends a little on what kind of message you want to send them.

"Official" website: https://bitcoincore.org/ and http://bitcoin.org

All others I mention here are public media where many people participate, including some of the Core developers (not always by their real name). Always be wary of fake user IDs.

Be careful that there are a lot of companies and groups with confusing names or even purposely misleading names, trying to give themselves credibility.
