Syntax and a bit of help

I'm writing a poem that I have to set to song. I know that the EXACT
pronunciations for Late PIE are not precisely known, but from how they
seem to be written, I at least think it possible that were we to speak
to an actual Proto-Indo-European, he (or she) might understand what we
were saying like a speaker of French might understand one of Italian
or Portuguese.

However, some of the words have left me flummoxed, ESPECIALLY the
accents, which are rarely mentionned. Is it possible that I could have
some help in completing this in as close to a syntactically correct
form as is possible? Please?
