My first Gui Dialog Box

Just when back from Penang. the air at the bridge stinks. the food at the island is nice however. Skipping that apart. After a holiday i managed to convert instead of using console mode my apt over https installation is done using zenity. Which i thought pretty cool since ubuntu users tend to prefer the gui over console.
Here is a snapshot of my zenity snapshot.
Now i got this problem . it works with apt-get aptitude but not synaptic. I'm still searching a way so that we can use synaptic + https_proxy. so far i got no luck :( . here`s the snapshot

1.First user will be prompt


2.Next the script will lunch it magics

3. Works with aptitude and apt-get but not yet synaptic
