Can I determine which process sent my window a message?

I have a window, and I am looking at the messages that are being sent to it using Spy++. Is it possible to determine which process sent my window a given message, if it indeed was sent from another process?

No, Win32 window messages do not contain information about where they were sent from (unless that information is specifically included as part of the message WPARAM and/or LPARAM components).
