Arnie;
Looking at the music in my fake book, it would be pretty straightforward to play an accompaniment to the song. There's a hundred ways to do it, but at my basic level, I would play it with the root (base) note on one finger on my left hand, and play the chord with my right. In other words, the first measure says it's a C chord, so I would play the C note one octave below middle C, and the C triad (CEG) with my right hand. I'd probably start at middle C with my right hand and see how it sounds. Then the next measure says it's a Cmaj7, so I'd stick with the C in the left hand and play the Cmaj7 with the right. Next is the F, so I'd play an F below middle C with my left, and F triad with my right. Continue on with the rest of the chords in such manner.
I have some music from musicnotes.com that denotes the accompaniment to be played with the top two notes of the bass clef alternating with the root note...in other words EG,C, EG,C for the C Chord...then GB,C for Cmaj7 Chord, then FA, C for the F Chord...which is just an F Chord inversion. That's another way of playing the accompaniment although it may be a little bland without the melody.
Since it's 4/4 time, there's a lot of options to make it sound interesting, but the absolute easiest is just a whole note (four beats) each measure. If I wanted to make it sound like I was strumming a guitar, I'd probably use quarter notes, in other words, strike the keys four times each measure. That may sound like too much when you play it though. You just have to try it and see what you like. You could alternate (root, rt hand chord, root, rt hand chord), or use 1/2 notes, or alberti chording, or alternate root notes, or swing base chording, all kinds of things. Googling those terms will get you started, I think. It can be really basic, or really complex.
If I were REALLY good, I might try open voicing with the chording. I'm not that good. Not nearly. Probably not ever
Hope this is what you're looking for.
