How simple are we talking about when you say "simple frontend development"?
For simple personal projects I write all my own HTML and CSS from scratch. It's not particularly hard to write stuff with low to moderate interactivity from scratch and the infrequency that I do frontend dev means it's quicker to do that than learn whatever new framework has replaced the deprecated one I spent time learning a couple of years earlier (that's probably unfairly snarky but from an outsider looking in, it's hugely daunting and depressing when you see just how much churn there is).
The only problem with rolling your own is that you raise the difficulty for anyone new joining the project (if it's something you plan on opening up to other contributors) and CSS can be a bit a of trial and error to get right too.
However if you're just writing a few test UIs to interface with backend APIs you're POCing (which is what your question reads as) then it's probably easier to skip all the other frameworks out there and knock up something yourself.
