How to build a simple scientific QC software (beginner’s question)

Hi y'all,

Im thinking of putting together a quality control software for my field of science. Basic idea: 1. give a txt file as an input, together with some numerical parameters for the analysis 2. Software evaluates data: data wrangling and visualizations. 3. User can play look at the plots, maybe interactively alter parameters. Option to export (a) results in pdf or html format and (b) configurations used for the analysis/visualization.

The languages I know are R, Python, bash and Julia. Id like to stick to those 4

I know how to handle the backend (i think you call it that, like the calculations you want to have performed and stuff – like data analysis with the tidyverse and visualizations with ggplot). Front end i have 0 experience however.

I envision a gui that can be opened by executing a .exe file, it opens a window where i can drag and drop input files and some tabs where the results show up, this kind of stuff.

My question: which packages and tools would you most strongly suggest? Im willing to expand my horizon within the 4 languages mentioned, do you have some concrete advice how to best approach this?

I would just write a shiny app with R, but they're too slow and Id like to easily incorporate julia and python code, if thats possible..

Thanks for your help!

And happy easter/pessach/ramadan!
