A prototype page for simulating navigation between objects in a computer program. A selection of a distribution of presentation areas is received. A placement of first and second icon symbols in at least one of the presentation areas is received. The first and second icon symbols represent first and second objects, respectively, of a computer program. A placement of a navigation symbol is received. The navigation symbol represents a navigation between the first and second objects. Markup language code is provided for a prototype page. The code includes location indicating code corresponding to the distribution of presentation areas. The code includes picture code for first and second pictures corresponding to the first and second icon symbols, respectively. The markup language code further includes interaction code corresponding to the navigation symbol. The prototype page is capable of simulating the navigation between the first and second objects in the computer program.
