In our master bathroom I ran the wainscotings under against the bottom of
the window sill and then added the typical lower window molding on top of
the wainscoting and against the bottom of the window sill. Is that what you
are asking about?

Each job is different. Did something similar to this. I found
planing (using a jointer) the lower window moulding down a bit kept it
from looking "protruding". Each job is different. Most likely you
will need to rabbet some trim to get all pieces to overlap properly.

Bottom line: wainscoting first, trim after.
