If you're coming from Windows & Visual Studio, you might find Code::Blocks meets your expectations.
That was my experience; I tried a few others first, but they all seemed to expect me to do a lengthy tutorial before I could start doing anything interesting - and with a dozen IDEs to try, that could take days.
With Code::Blocks there were no hoops to jump through, and very little mandatory cruft to learn before I could be productive. I still prefer Visual Studio, but Code::Blocks can open my Visual Studio projects, and it doesn't seem to want me to waste any time, so it's the winningmost *nix IDE for me.
