Windows-like scalable panels in Unity?

Hi! I'm working on a relatively simple project and I would need to create different windows that have similarly scalable as any MS Windows window element, so if I click on its edge, I can drag it around with the window scaling with it, but only on the desired side. I would start with putting gameobjects to all four edges and interact with them, but this feels a bit cumbersome. Is there a better, unity-suported way to do this? Or if not, how should I approach the problem? Thank you!
