create a (local) HTML webpage which uses a .jar file

Question

I'm very sorry for the possibly confusing title and also for the following expressions, as I'm a complete newbie into coding.

Background: To make life a bit easier for our team at work, I would like to create a super simple HTML page which lists the most useful links to other tools in our company but is also able to send commands to a converter which exists as a .jar file (which requires different arguments - see attached pdf). Currently, we are running the specific command in the standard command prompt window in Windows to convert files into different formats.

Basic idea: It would be so cool to have a very simple GUI (incl. some buttons + input masks). The attached PDF should explain it quite well IMO. I would then send around the package (containing the .html + .jar converter files) to my colleagues, so they can open them locally on their PC. If this works out fine, I would love to run this page in on a local intranet web-server, so everyone in our company is able to use the page (without having to store anything locally on their pc).

I know that it might be a bit too much to ask for, but it would be great if you can give me some kind of how-to. Or maybe someone has some nice hints where to start with. I know a bit of html stuff. The most hardest part to me is to execute the inputs with the .jar file.

I would be really happy if someone is able to help out as it has always been a tiny dream to have this "tooling page".
