Note that you cannot add a webserver with the admin web interface, you need to use the command line.
Essentially this task is performed from the plugins install dir. There is a facilitating script there called configurewebserver1.bat.
The webserver might not have been installed properly because of pathing. If you install WAS and then reboot and then do HTTP server and plugins it might work.
This script calls a couple of files that might need to have a path modified. Please see my edits below:
D:\IBM\WebSphere\AppServer\profiles\AppSrv01\bin\wsadmin.bat -f
D:\IBM\WebSphere\AppServer\bin\configureWebserverDefinition.jacl webserver1 IHS "D:\\IBM\\IBMHTTPServer" "D:\\IBM\\IBMHTTPServer\\conf\\httpd.conf" 80 MAP_ALL "D:\\IBM\\WebSphere\\Plugins" unmanaged nsgshsjdnsp02u.XXXX.local nsgshsjdnsp02u.XXXX.local windows
From above, I had to path the wsadmin.bat file and the configureWebServerDefinition.jacl file.
Note that this is a 25K file, you don't wanna create one of these yourself!!
Output of the script looks like the following:
