GOLANG - Get property of struct by name?

I have this struct definition :

// Two columns, both strings.
type ExampleStructItem struct {
    Firstname string
    Surname string
}

and I have this slice of column names :

columns := []string{"Firstname", "Surname"}

and I am essentially trying to loop through my slice of column names, and then perform reflection on the corresponding struct to get information about the properties, such as their "Kind" etc.
