Not the planet, but you can see the primry star it orbits. It is in the constellation Libra an easy sight from anywhere on Earth.

The star Gliese 581 is magnitude 10.56, so you can see that with your telescope. Of course the planet itself cannot be seen even by the largest telescope in the world. Its existence is inferred from subtle changes in the light of the star, specifically a small regular change in the Doppler shift of its spectrum.
