how to connect srm crm erp to netweaver portal

Dear experts,

We have just installed SAP ERP ECC6.0 Ehp6 (ABAP Stack) + SRM 7.02 + CRM 7.02 for our customer. To use these applications, user need to use:

- NWBC client for SRM

- Web for CRM

- SAPGui for ERP

The requirement is to offer one single point of access to these applications. I think (but I’m not sure) SAP Enterprise Portal can do this. I would like to know if it is possible to integer these three application to SAP Netweaver portal 7.3 and how?

Thanks in advance
