Is is advisable to use Alien carefully as you can get some unrewarding results on occasions, you may be restricted by the unavailability of dependencies which can happen a lot. It's always best to check first if there is a suitable ready built rpm or if the program can be easily compiled from source. It can be a life saver if there is something you particularly want but can't get by any other means.
Package Converter (requires Alien above)
There is also available a free GUI to use with Alien called simply 'Package Converter' written in Python by Foxoman.
Once Alien is installed as above, download package-converter-3002-2noarch, then install and run it as below.
