Req: "Mere dil ka tumse yeh kehna" from Armaan (chords or scale please)

Could anyone please post either the chords or the key/scale for the song "Mere dil ka tumse yeh kehna" from the movie Armaan?

Even if I just have the key/scale, I can try to figure out the chord progression. I just have such a terrible listening ear that I can't distinguish different keys/scales very well so I can't decipher this on my own... Thanks!

 

Does anyone at least know the key and/or the scale which this song is in? I can roughly figure out the chords once I know the key...
