in principle you can do that by using vector graphics - but the simplest and fastest way is still using bitmap frames as mentioned in the article Drawing rounded rectangles.
I hope this helps.
Do we need to give rounded edge png for achieving this?
Yes. You have to create the necessary PNGs. For this purpose you use a graphic editor (e.g. GIMP, Photoshop Elements, Affinity Designer, etc.).
