Workspaces are super old, basically as old as X itself. Pretty much any Linux DE has always supported them one way or another.
I think widgets may have been done before KDE too. Depends how you define them I guess, if it's just dynamic output slapped on a graphical bar they'd definitely been done.
Crazy, already got virtual workspaces and a desktop containment with widgets

xeyes was technically a desktop widget I suppose. Desktop widgets started pretty much with X11.
