Real Admins know and love the powerful command line.
GUIs are for Windows lovers...
Here's the steps to run a GUI on OpenBSD
1. Install openbsd (use the FAQ on www.openbsd.org to install)
2. After install, reboot
3. After reboot, login as a user (you should have set one... NEVER use root)
4. type 'man afterboot' and read it
5. to get a GUI, type 'startx' at the prompt, this is cwm, but you can install any of the other excellent window managers (I use scrotwm)
6. If you require a bloated GNOME or KDE, you can install it using pkg_add (follow the instructions on the FAQ)
Really, all it requires is 5 minutes of work to read the FAQ. Everything is in the FAQ, or in the well written man pages. OpenBSD even treats misspellings in man pages as bugs, and with the same severity as other bugs...
If you still have a question, e-mail firstname.lastname@example.org... you can also e-mail email@example.com, but be sure to have done your homework if you ask a question...
