Oh, OK. But I'm didn't understood a half that you said. I'm don't know how to code and where the code.
P.S.:
And as far as I understand, a particular dwarf can not be cured? Only all?
no just that the only scripts provided with DFHack can either cure all or have to be targeted by a cursor...
So you would have to write your own variant of it, if you want it to target an individual unit that performs a reaction.
Basically the reason I think you are getting low responses is because you haven't learned to code yet. To make serious changes to Dwarf Fortress requires some experience at coding, you need to learn at least basic lua scripting, DFHack data structures, and Dwarf Fortress raw token coding before you can really start producing for the community, and at your current stage, you just wont be able to get it done on your own. There are many resources, linked to here in the forums and in the DF wikis to gain that knowledge, it will take time, 2 to 3 months if you keep at it, but its not impossible to learn, (I've only been working on coding for DF since October last year). Seek the documentation, and try to figure it out, show some initiative.
Basically most of the coders, here, are involved in their own massive projects and don't have the time to do more than guide you in the right direction. I can program what your asking for, but my own projects are in need of updates and if I take the time to do your project (and everyone else's as that's the end all, be all of the situation) then I wont be able to put out my own work in any reasonable time scale.
