Newbie with lots of questions

Thank you for accepting me in this list.
I joined here, because:

    * I've been trying to change my Access Database to Linux
    * Access is the only program I need to use that I can't migrate to Linux
    * Access is the only obstacle I've to migrate completely to Linux
      and forget FOREVER of MS and Windows

I create this Access DB several years ago to have a control of my 
pediatric patients. It works fairly well, and I've adapted to my daily 
practice needs.
On the other hand, some time later I discovered Linux and Open Source 
programs, which I use in Windows.

My question is if MDB Tools will help me migrate my Access DB to Linux. 
Which are the first steps to take, you consider I should take or, do you 
know of a database program with a GUI Interface that works in Linux?

Thank you for your patience and for your help.
