I've worked on the java-html-web services side of a such ibm -> x86-64
system (a "local" italian ERP).
They started with a MVS COBOL system, then ported it to AS/400 COBOL.
With screen-scraping libraries came a web application with "hooks" for
host spools and SQL queries management (job queues were handled on host).
After that they added (aside TN-5250 and TN3270 channels) a custom
communication channel for windows COBOL programs (coding screens,
function keys, field contents) and an architecture for jobs, job
queueus and spools (mainly in XML).
It was a big task, but it still work well today after maybe 20 years.
There are (still today) 4 platforms : mainframe spanning from VSE to
zOS, AS/400, windows and linux, and the core is written in a "portable"
COBOL (and bulk of customers run their system from ONE web server on
the cloud !!!)
Back to your question, you need (not in that order ...) :
1) a web interface
2) a channel from COBOL to web
3) maybe a screen converter from video maps to interface programs
(with some common area in between)
4) a job system architecture
6) a spool architecture
"And after a while, you can work on points for style" :
- database query system
- web interface "bell and whistles"
- xml batch jobs
- web services
Watch your step : a drawing of the whole system filled a kitchen
table ...
