Macro to open a URL using IE

Hi All,

I got the below macro which uses IE and open the URLs. I want to create a userform with listbox with radio button and commandbutton on the same which will help me to connect to each url when I select the same in listbox and click on the commandbutton.

Sub DoBrowse1()
    Dim ie As Object
    Set ie = CreateObject("Internetexplorer.Application")
    ie.Visible = True
    ie.Navigate "www.google.com"
End Sub

Any suggestions..
