not sure if there is anyone in this forums who can write chords. however, if you try, you can figure out the base chords. Chords are nothing but notes that are played in sync (of course musically).
for example, if the song is on C major scale, the notes C and G would be in sync with the song always. This is the base for music theory. If the song is on D major scale, the notes D and A would be in sync with the song always.. and so on. Similar manner you can create chords. The only criteria is that the chord you are producing should match musically and note wise - this should be the primary thumb rule while figuring out the chords.
