is there a bedwars plugin cause i wanted to add bedwars on my server

No, there is no plugin for bedwars avalible that has been scripted by someone and is out to the public. You would have to code it yourself. Also, it might be a little hard to create a legitimate bedwars plugin for ClassiCube. This is not Minecraft, so I doubt you could create a server-side plugin that lets you play High Pixel quality bedwars. And even if you were able to get that plugin, it would require more resources then one plugin.

either learn how to code or wait a long time for that to be made

I have make bedwars in Vexia Map Build server, come !
