#3 GUI elements

[AbrahamCC]

Field text is already done but it is needed more GUI elements

Alert message (only 'ok' button for example 'invalid url'
Simple message (no interaction for example 'loading...')
Confirmation message (ok and cancel eg 'Do you want to...')
List message (choose one option dropdown list? and/or radio buttons)
List message multiple (multiple options dropdown or checkbox buttons)
