Drawing rules/lines with rounded caps - possible with built-in macros?

Hello, 

A style I'm replicating incorporates a few lines with rounded caps in the page layout as a design element.

I'm currently using fbox but wanted to ask if there's something a little less hacky than this: <fbox;100;11;;44.10p;1.5q;0q;non;0q;0q;3000>
