I had a semester of HTML, Visual Basic, Visual C++ in undergrad. Along with some exposure to Java. Some of it stuck.
I've taught myself a little bit of UNIX/Linux shell scripting, just enough to be dangerous.
Oh yeah, forgot about HTML, did some of that in my Web Design class as well. :)
I gotta say, to me, the easiest of all the ones I've done is Visual Basic. From what (and considering it was only a semester, probably very little) I did with it, you basically start out putting something together visually, then you jump "behind the scenes" to make it work how you want to. To me that was just far easier to conceptualize and grasp then say, Java, where it's do a flow chart, put in one line of code at a time, watch as your program not work, spend an hour just finally realize you put a damn colon in the wrong place, repeat.
Problem is though, I'm not really sure if there's ultimately that much you can do with VB....
