Any general purpose language will do. Basically everything can be 
expressed in any language, through some tasks are very cumbersome 
in tasks they are not designed for.

C and C++ have steep learning curves, and tend to be better for 
professionals than amateurs. That does not mean C/C++ usage is 
what defines a pro. Even php, famous for being simple to learn 
but often hated by professionals, can be used professionally.

Don't worry, learn to apply one language in practice and you'll 
usually figure out automatically how to apply any language you 
will learn. Well, sometimes when you transition to a new language 
you should learn new ways to do thing, because the new language 
is better suited for those than your old language.

Famous example is that C programmers that transitioned to C++ or 
Java in the 90's were encouraged to start to thinking in object 
oriented manner. They did not strictly have to, as C++ and Java 
can be used for same programming stye as C, and C can do sort-of 
object-oriented programming, but object-oriented designs were 
(and are) so much easier to implement in the newer languages that 
in practice, object design should be used a lot more now than in 
the 70's.

Basically, GUI libraries call the operating system API that is 
different for different operating systems.
