I'm new to programming; however i have been able to read and research the programs i need to set-up for a GIS system. I chose to use Geoserver (as WMS) Postgresql, postgis, Qgis and Openlayers. 
I am setting up a web-based map platform. I have been able to install ubuntu on AWS on which i successfully installed postgresql and postgis. However, am finding it hard to follow tutorials through a command line as I need to see the file structure, etc as well as pgadmin3. is there any way i could access the instance through a gui to perform further installations and tutorials?

Please advice,
