If you wish to write Windows applications, you would probably need to learn Visual C++ or C++ & Visual Basic.
I can program C, C++ & Java myself but have avoided learning much VB. Unfortunately, no one can just give you a quick tutorial via a forum on how to learn any of these. VB is extremely easy because it's fairly limited but C & C++ take a long time to master.
If you search the net though, there are plenty of free tutorials you can download on all of these languages.
