Multiplatform scripting language for projects in Fortran and R

I am currently working on a research project with a large Fortran code base. Ideally, I would like to write a script taking the output of the simulation, written in FORTRAN, and execute it through tracing and analysis scripts, probably written in R. Furthermore, I would like to maybe write a Python script to generate test cases. . I'd use bash to link all these programs together, but my PI runs on Windows and I'd like it to also run my code.

Which scripting languages ​​would be appropriate to combine these programs while remaining independent of the platform?
