If I made my own little application, it is probably not as secure as something well tested and mature like the applications that come with the Workstation

Run your application inside sandbox and/or apparmor. by that even if it gets hacked there are no previliges for your application to attack your entire workstation. (though we do that as well for many things installed in whonix)
