HI,

 

i would like to create a new window like the one for party or clan invitations.

 

in the new window will have a question and they must press to only one button.

 

if they press to the button they will receive some things. (this is easy to do)

 

do you know how to create a new invitation button?

Making new buttons; New windows like the packet windows;etc require client modding.

Your only chance is to make a Macro,add it to the skill's bar by default and make it popup a normal html window.
