GUI (specific frontend) for Postgres on a PDA -GTK or Tcl/Tk? - Mailing list pgsql-interfaces

Please I definitely need an advice which of these tools is better - it 
means easier and faster to learn.
I have a middle-large experience with C , but although I am worried of 
robust architecture of Gtk+ (special datatypes, functions, etc.).
It seems to be very powerful but hard to get in.

And Tcl/Tk (or do you know about any other -- better possibility)
means to learn it from scratch ....and it's interpreted --maybe not good 
for a PDA (common iPaQ)

Many thanks forward;
