Dear Egemen,
Enumeration data type is an appropriate to represent a values of a fixed set. In addition, Mendix platform also provides you with the capability of assigning a specific image to each enumerated value which you can apply on UI in order to present image rather than a caption text.
Putting data set on UI is another topic which can depend on several aspects. In general, you can implement this by using a datagrid or a list view.
Hope it helps,
Istvan
