Use your marquee selection tool with a feather of around 20 pixels depending on the size of your image. When you've made your round-cornered rectangle, go Edit then select Stroke. Pick your flavour of width, colour, etc etc.
That is not the correct method, because that will not only round off the corners, but also create a very feathered and faint border. That is probably not what the OP wants. An easier way is this: Increase the canvas size just a little, so that you can select the entire image without selecting the edges of the canvas. Don't feather the selection. Go to Select - Modify - Smooth and use 15 pixels or more (depending on the size of the image). That will round off the corners of your selection without introducing any feathering at all. Now you can use Stroke to make a border around the selection.
Another technique, that shouldn't require resizing the canvas, is to start with a rectangular selection smaller than you want the frame to be, then Expand Selection to the desired size before painting it.
