You can use the WaitForUserDialog class that was added in ImageJ  
1.39r. For example

     new WaitForUserDialog("Do something, then click OK.").show();

or

     new WaitForUserDialog("Title", "Do something, then click  
OK.").show();

if you want to use a dialog title other than the default "Action  
Required".

In a macro, use

     waitForUser("Do something, then click OK");

or

     waitForUser("Title", "Do something, then click OK");

Add new lines characters ("\n") to display multiple lines in the  
dialog, for example

     waitForUser("Do something\nthen something else,\nthen click OK.");
