Que es la diferencia entre "Me gusta" y "Me gustan" ?
could you explain it in English ? 
could you give me few examples for every case?

Answer

Ok, singular and plural, But.....the problem to undestand the Spanish's use is the different structure in English and in Spanish.
In English, the subject is the person who likes. I like something.
But in Spanish the subject is the think: Algo (something, subject) gusta a mí (person, object)....Really we say : Algo me gusta.
The concordance is subject-verb:
Singular: La manzana me  gusta (subject: la manzana)
Plural: Las manzanas me gustan (subject: las manzanas) (gustan = plural because manzanas = plural).

Answer

Hi Salat, the different is the object what you like, if it's singular me gusta, if it's plural me gustan, haven't importance the subject.
No me gusta el frío 
Nos gusta comer 
Me gustan los niños 
No nos gustan las fiestas.
