Ndiswrapper IS available for RedHat. Did you try to install it using yum? Also, be aware that if you're not PAYING for RedHat enterprise linux, you won't get access to the RedHat repositories, updates, patches, etc. Unless you have a very specific need for RedHat enterprise, you should either load CentOS (essentially RedHat enterprise, but free, and community supported), which will give you the patches/updates etc., or load another distro that's more focused towards 'consumer' hardware. Ubuntu is a good one.
The link that was posted is for Ubuntu, but the basic instructions still work. As smoker said, you use yum instead of apt-get, but again, unless you're paying for access, you won't be able to access the RedHat repos to install ANYTHING.
