Text to JPG. How to

[vector]

Still new at this and just wondering if I should pursue this little side 
project using Python.

Objective:
request text from user via gui(tk entry box)
convert text into a jpg (160x120 lowres)
save jpg

enhancments:
display preview of jpg
abilty to change fonts colours etc
recall previously saved text's

Q how difficult would this be to implement using Python,tk and PIL ?

I pretty much have tk sorted out but havent looked at PIL yet.
not sure how to go about converting text to jpg
