It's really not that hard to compile things, maybe you ran into problems with errors or missing dependencies in the past. If you have the file ndiswrapper.tar.gz, for example, all you do it:
tar zxvf ndiswrapper
and it should be all taken care of. If it uses a different install procedure or the above steps give you errors, a quick post here can probably solve the issue. It's good to learn to compile from source even if you're using a distribution that doesn't require it. There are always a few programs that aren't available in the correct package for your system, and source is almost always there.
