You might want to have a look at

https://github.com/alt/tex-overview/blob/d9f27338d9c694fe14240aff150a048a086ba2ec/tex-overview.pdf?raw=true

There I have collected everything related to TeX that I could find, 
including short explanations and sources where I found information.
[a short answer to your question is: ANT and HeX are written 
independently from TeX, but neither of them is useable at the moment. 
NTS was planned to be a TeX written in Java, but is now declared dead. 
The successor of NTS, εχTeX, is in version 0.0 …]
