Well if you think Launchbox is not user friendly, then you should take a look at some of the other frontends on Windows, they are far more difficult. As for MAME it really is simple, download a full MAME romset, newest is always best, in Launchbox go to Tools/Import/Mame fullset importer and just follow the instructions, which are, where are your roms, what do you want to call the platform (Arcade is the default and recommended), do you want Launchbox to download and configure the emulator, and thats it, let it do its thing. However, it is ALWAYS advised to make sure games work outside of Launchbox first, as a non working game is a non working game, and nothing Launchbox can do about that.
