You can go through this link - http://help.sap.com/fiori_bs2013/helpdata/en/7e/4076547363054ee10000000a423f68/content.htm?frameset=/en/fd/f50255c0c6b46ce10000000a44176d/frameset.htm&current_toc=/en/40/1b675374bc6655e10000000a423f68/plain.htm&node_id=8

Here under the section ABAP Front-End Server for SAP NetWeaver 7.31 with SAP UI 1.0 you can find the exact component versions that need to be installed on the front-end server along with the gateway components (GW_CORE 200 and IW_FND 250).
