Can you make this mod translatable?

Yes, I can make this mod translatable. I don't know how useful that will be since the mod happens before players can change their language option though.

What if players already have set their language before installing the mod while playing vanilla MC (like myself)?
Otherwise they would get the translated message once a new Java update is released.

That's a fair use case. I was thinking this mod was mainly used by modpacks.

Okay, I have made this mod translatable. The GUI bodies use HTML so you can actually change the layout a fair bit. Please try to stick to the same format though.

Okay, thanks! I'll bear that in mind when I translate it.
