I know exactly what I need. I just built a task manager in C with GTK+. It uses the theming built into GTK to allow users to change themes while the program is running but it's too memory heavy for my taste. I also have a background in web dev and understand how to build for accessibility. Currently the memory allocated for every single process on my computer is right though I'm already thinking of scaling and hidpi as another thing I need.
