while not strictly 'programming languages' the following should ensure good career:
download one of the free BPM flow diagramming products. from tibco or lombardisoftware.com
you'll have to register, free and maybe suffer a sales person call, tell them is for yourself.
Eclipse is hot, download their ide free.
It is not just for java. now have eclipse for visual studio's languages I hear. I also hear PHP is real popular. Both will run on systems other than m$
You can download informatica power center (along with an oracle database to run it against, and dw product to load it to) from otn.oracle.com, you need to register. Have a free toad for oracle with that, and learn to use it. (Yummy, toads)
DWs are and will remain popular despite 'dw appliances' like netezza - still needs etl pgmg, and qlikview - missing critical parts of dw, so only use will be in small companies.
That said, you can register at qlikview and learn about it thru their videos.
learn the basics of IT proj mgmt and you'll more likely be hired as pgmr. add a smidgeon of security with security+ or cissp online e-learning. even if you don't get their certs is good to learn about encryption, security, which is used in all network pgmg.
learn reporting tools crystal is easiest but not trivial once you get beyond basic reports, subreports, embedded reports in vb, complicated functions, the sql it generates.
Learn sql but you should not generally be programming in sql, it should be generated for you by visual products generally. you should know enuf to figure out if joins correct, or where error is, and prods like winsql to check if no indexes present on dbs causing a join to hang with whole-table scans then. crystal uses vb as the function language as an option. i prefer their syntax.
learn how to use one of the other reporting tools like cognos or microstrategy. webfocus is popular.
and as others mention, vb is good. a bit cryptic with the object oriented stuff but less of learning curve than many C languages.
javascript is just plain useful since embedded in most browsers. you should know a bit of html syntax also.
you can goto sites like ittoolbox.com and read about what people in language or topic you think you are interested in do on a daily basis, and could you answer the help questions?
acm.org has tons of classes free if you join. ieee also (computer.org)
browse vendor websites and replay their canned webinars.
download trials and actually install them and use them heavily for the free period. some dont' expire.
