How to set up a single entry to SAP R/3 systems ?

Hello,

we have just installed EP 6.0 SP2 with CM.

We would like to know if there is an "easy" way to create an iview (?) able to provide a single entry point for users to all SAP R/3 systems we have in the company.

For example, let's imagine an iview with as many buttons as R/3 systems : pushing a button would allow a connection to the corresponding R/3 system (main menu).

Do we need to perform development for this ?

Does a tool provide such functionnality ?

Thank you.

Regards
