Create an automate software

I wanna be able to automaticly register some tourneys on a poker software. In details, i wanna be able to press a key and have all the registrations i need done. The registration process is : 1st : select the stake that i'm playing. 2nd : auto click on register. here a pop up will show. In the pop up window, tick a " okay " box then click again on register Finnaly, a new pop up with a " okay " bouton to click. I wanna be able to just press a key and have all the previous action done without me having to do anything. I'll provide the software that i need registration on. Thanks !
