 lo que puedes hacer es crear una instancia de un form

Código:
Sub Main()
    Dim x As Form
    Set x = New Form1
    x.Show
end sub


en este caso el proyecto tiene un form "Form1" y lo que hago es crear una nueva instancia de ese form

CeLaYa te agradezco mucho pero eso es para duplicar un form, lo que necesito es crear el form desde 0
