For a long time there was the Pinnacle Deko family of CG boxes and software. AVID bought Pinnacle several years ago, and I think they're still selling some of the products. There were several products, some were software, some were hardware based.
There was also a plugin for Premiere Pro called TitleDeko. The whole family of Deko products was very intuitive to use, and allowed easy creation, by putting a still of the clip you were working on in the background of the CG interface. There were tons of style possibilities, animation was possible in some versions, and even playback. I think AVID bought the Pinnacle Deko line to kill the competition, but you may still be able to get it. I worked on both the TypeDeko boxes and software for almost 15 years, and loved them.
