gee dude,
looks cool

I don't know if it's functional,
never had much luck with gnutella clients (xolox was best experience so far)

some remarks:
+ nice buttons
- ugly other buttons (minimize/max../quit/m$-ico's)
I'd suggest going with either classic windows, or fancy new style (like those cool buttons) with also fancier borders
+ configurable with .ini, GREAT :-)
- no icon in taskbar, just "Peernha". it makes it look like a popup ("An error has occurred: Close/Ignore", or whatever)
- no ability to kick it to systray
if in systray, you might have an indicator there (just an int) of how many files you have left to download (you will know if a file is done trough the n--, and when all done if n==0
- download etc.. buttons don't show that they're being pressed, nor does the mouse
+ I love the stats at the bottom of screen
+ Share_Addinfo

that be all for now,
keep up the good work
