pgadmin3_93 on centOS-7

Trying to install pgadmin3 on CentOS-7 via yum, but the install requires
wxGTK (see below). wxGTK does is not available in my repos and when I try
to install a wxGTK rpm, I get a bunch of other dependency failures (see far
below). Has anyone been successful in installing pgadmin3_93 in CentOS-7?
Is there a repo for wxGTK?Thanks in advance(dot)[root(at)chopin tmp]# yum install
