Well you could automate that by using steemjs, get all the comments, look into the text to see if there is a [1] or a [2] inside of it, then check if they indeed voted on your post. If so, execute a transfer to them.
You'll find a snippet to transfer here :

For the rest you can find the functions here :
https://github.com/steemit/steem-js/tree/master/doc
to get the comments on a post use : steem.api.getContentReplies
To get the votes use : steem.api.getActiveVotes
Thanks for reply, @howo.
Could you suggest me a dummy guide to steemjs, snippet and steem.api ... 30 years ago I was a programmer, but now I have to start from scratch!
I really appreciate your help and I thank you!
My primary need now is to make two cumulative payments: is there a novice-proof front end?
