you want to say I want write How do I make start page only or what ?
my question is if i make the design to my start page .......how I make it as start page and from it i will go to another page when I click start button ..............and exit the program when I click Exit Button .
Choose the start layout by changing First layout in the Project Properties.
Create a button, if clicked it will go to Layout. Using browser object to exit the game.
My suggest is to read some beginner tutorial, avaiable in other languages, it should solved many of your problems.
