Try 'ExitWindows', which is documented for Windows 3.0.  What isn't
documented (but will be in the next release) is that you can also
have Windows exit, then restart (just like Windows setup).

The first parameter to 'ExitWindows' is a mysterious "reserved code".
Turns out that using 0x42 for that code causes Windows to restart.
Set the code to 0x0 for Windows to exit back to DOS.

Note that 'ExitWindows' asks each app if it wants to shut down; if any
one says "no", the call fails.

This will get you the "turn itself off gracefully" part; you have to do
the rest (i.e., figure out what events trigger the exit).
