Creating a PHP Instagram bot

Hey, guys. I was thinking of creating a bot for Instagram using PHP. Is there any limitation to why I can't do it? I mean Massplanner and Follow Liker are made using a desktop language.

And looking on the web, I can't see people sharing any reliable bot like instabot py for example?

Also, how long does it take to create a good bot like Massplanner? Some people said 3 to 6 months. Time investment is not a problem.
