Ive used Rosetta Stone for Turkish and it will teach you tourist language abilities: how to ask for food, toilet, costs, please, thank you, etc. It does that well enough, although it is costly!
If you are wanting to study the biblical languages for biblical studies though, I fear you may be sadly disappointed. Modern Greek is different than Koine, and although I don't know definitely, I would assume Hebrew is the same.
Machen's New Testament Greek for Beginners is a classic on the subject, and can probably be picked up used for a reasonable price; I got mine at Half Price Books for 2 dollars or so a good many years ago. I don't know of any interactive, multi-media series for Koine Greek, but I'm sure some of the other language scholars can help further with recommendations.
Rosetta stone is wonderful though the modern vs ancient would be a problem. It's addicting. I took 5 months, not full time, to get through 2 discs of French. Thereafter I could play French scripture cassettes, familiar NT stories, and understand. That enabled me to spend hours and hours listening during commutes and housework, absorbing an understanding of the language effortlessly.
As regard Hebrew, I'd suggest materials put out by the Jewish community to teach their children. I found a lot of delightful resources in a Jewish book store in Chicago. One of my favorites was "Hebrew through pictures."
