You would be able to make a small gif file with rounded corner in version 6 & 7 of Paint Shop Pro. I don't remember about version 5. You can also make the gif file in Image Composer, which came with the stand alone version of FP, so you may already have it instead of having to purchase more software.
And if you happen to have Photodraw, you could make them there also but I am not sure about making them transparent there.
With any of the software, it doesn't immediately create what you are after. It will require some knowledge of the graphics program.
