C++ doesn't have an interface to allow you to create any GUI code, but you can use external libraries to draw the GUI stuff and control it with C++.
For example here is a gui application in C++ using the QT library:
int main( int argc, char **argv )
QApplication a( argc, argv ); //create a window object
//create a button object with the text 'hello world'
QPushButton hello( "Hello world!", 0 );
//set the size of the button
hello.resize( 100, 30 );
//add it to the window
a.setMainWidget( &hello );
//enable our button to be shown, by default it is hidden
//show our whole window
But judging from your post, I do not suspect that you have grasped most of the concepts in C++, so I would suggest to start doing more projects and not worry about gui stuff until you have a solid grasp of C++. How much of its concepts do you know, for example arrays/if-else/classes/structs/templates?
